Mac's young technician
sidekick Barney decides to one-up the do-it-yourself television repair books that were flooding magazine
pages those days by writing a series of do-it-yourself surgery books. He figures if the other guys can
get rich by convincing Joe Sixpack that he can easily fix problems in his TV set - where potentially
lethal voltages lurk in every corner - in as little as five minutes while saving hundreds of dollars from
those rascally shop owners, then surely those same people might buy his books for removing your own
appendix or tonsils. Deny the greedy doctors of their fees for such simple operations. Barney might
have been the first to dream up the concept of the now-popular "for Dummies" series of books.
Mac's Radio Service Shop: Spring Fancies
By John T. Frye
Mac and his office girl, Miss Perkins, stood side by side looking
out of the window of the service shop at the ambling figure of Barney coming back to work after his
lunch hour. As the youth walked slowly along, his red hair flaming brightly in the April sunshine, his
freckled face bore a look of dreamy introspection.
"Ah me," Mac sighed; "what wouldn't I give to be young again in the spring-time!"
"Yes," Miss Perkins said with an echoing sigh. "All you need is a look at that rapt expression on
his face to know how true are those words about in the spring a young man's fancy lightly turns to thoughts
Barney floated through the door and gradually allowed his eyes to focus on the faces of the other
two. Then he spoke in a voice of quiet awe:
"I have just been the recipient of a beautiful thought!"
"Blonde, brunette, or redhead ?" Mac inquired solicitously.
"Whatever are you babbling about?" Barney asked with a puzzled frown. "I mean I've just figured out
how I'm going to make my first million dollars."
"Thoughts of love," Mac quoted mockingly out of the corner of his mouth to Miss Perkins. "And pray
tell us," he continued to Barney, "just how you are going to harvest all this lettuce."
"It's a lead-pipe cinch," Barney answered confidently. "I'm going to write a book entitled 'How to
Remove Your Own Appendix, or That of a Friend or Member of Your Family, Using Only a Discarded Razor
"Hm-m-m-m," Mac said slowly; "I see you like a short snappy title anyway. Where did you get your
inspiration for this future best-seller?"
"At the lunch room magazine rack this noon. I was leafing through several of the magazines that try
to give popular explanations of various scientific and mechanical achievements, and I ran across quite
a few ads for books that promised to tell the television set owner just how he could repair his own
television set. Right then I decided that if you could tell a guy who didn't know from nothing about
radio or television how he could locate and repair any one of the thousand and one things that can get
wrong with a TV set, telling him how to perform a single operation like an appendectomy ought to be
"But," Miss Perkins objected, "if the TV instructions are a flop, all the guy will have is a botched-up
set; but if your surgical instructions go wrong, he will have a candidate for a harp. That's too dangerous."
"How safe do you think it is to encourage an untrained person to go prowling around in a TV chassis
carrying various lethal potentials up to 15,000 volts and better?" Barney demanded. "For years radio
magazines have been warning technicians, who are already familiar with high voltage circuits, to be
extremely careful to avoid shock in work on television sets; but these books blandly egg the set owner
on into wading right into his receiver. Some of them try to protect themselves by saying there is no
danger when instructions are followed, but any technician who has had any experience with the ability
of untrained people to follow directions in dealing with electronic equipment takes a very dim view
of the average person's ability to follow instructions. Look what happens when most people try to take
the tubes out of their little a.c.-d.c. sets and put them back the way they were, even when they have
a tube diagram to help them."
"You've got a point there," Mac agreed; "but leaving the danger angle entirely out of it, how much
help do you think these books would really be to the average owner of a TV set."
"Why they would be a wonderful help," Barney said with a straight face. "They promise to show you
how you can repair anything from a shorted picture tube to a set that won't stay in sync in from a few
seconds on the comparatively simple jobs to up to five whole minutes on the really tough ones. Just
think of that! Why it often takes poor old inefficient me, who never read one of those books, almost
five whole minutes to get the back off some of the receivers that use a whole handful of woodscrews
to hold it on."
"Guess we'd better buy some of those books and read 'em," Mac suggested wryly.
"We certainly should," Barney blandly agreed. "The fellow who has one of these books needs only a
screwdriver to make all of his repairs. There you have gone and wasted better than a thousand dollars
on your scopes, sweep generators, vacuum tube voltmeters, bar generators, tube testers, and service
manuals. After we have studied these books, we can sell all of that expensive and unnecessary equipment
and buy ourselves a nice new screwdriver apiece and really settle down to turning out the TV sets. Since,
at the outside, we shall have to spend only five minutes on a set, we'll really make money fast. As
it is, we often waste three or four hours running down a tough intermittent or doing a complete job
of realignment. Come to think of it, we can let Matilda here read the books, too, and then she can fix
sets just as well as you can, for experience is entirely unnecessary, and all of those years that you
have spent studying and working on electronic equipment have just been wasted."
"Tsk, tsk! What a pity!" Mac exclaimed with a broad grin. "Better had we get one of these books at
"I'm not sure a technician can buy them," Barney said darkly. "The writers of these books do not
trust radio and television technicians. In fact, they encourage the set owner to buy the book so that
he can avoid being 'soaked' by independent repairmen. I think I'll use that line in advertising my own
book 'Don't let the doctor gouge you for performing a simple operation.' I'll argue; 'buy this book
and take out your own appendix. No experience necessary.' "
Miss Perkins looked desperately from Mac's faintly-smiling face to the dead-serious one of Barney.
"Mac, how can you stand there and encourage the boy in such a mad idea as writing a book like that?"
she demanded. "Why he scarcely knows enough about surgery to cut his own fingernails. You know he would
never be allowed to publish the book. It would be murder!"
Barney strode slowly and deliberately over to the wall calendar and with a circling thumb and forefinger
ringed the date: April 1st. "April Fool, Matilda!" he shouted as his face broke into a delighted grin.
"You mean there are no books like that about television?" she asked with a suddenly rose complexion.
"No, I mean I was just joshing about writing a book myself. I was not kidding about the fix-it-yourself
books on television. "
"I've seen some of those books myself," Mac broke in; "and the better ones are not really too awful.
They do not encourage the set-owner to take the back off the set at all. About all they do is tell how
the size and linearity controls can be used to correct minor picture defects and to give some pointers
on orienting the antenna to get rid of ghosts, etc. When more than this is required, they recommend
that a technician be called.
"On the other hand a few books are appearing that attack technicians as being crooks and gougers
and blatantly assure the set-owner that he can repair practically anything that goes wrong with the
set without the use of instruments. That, of course, is a deliberate misrepresentation. The fact that
a money-back guarantee is given with some of these books does not change this fact in the least. That
money-back business is an old dodge that takes advantage of the fact that not one person in a hundred
will bother to return a low-cost item for a refund even though he is not satisfied with it."
"I don't imagine
you are much concerned with the business that the sale of these books will take away from technicians,
are you?" Barney wanted to know.
"Not at all," Mac replied quickly.
"As you know, after the guy has fouled his set up but good, he will call us; and then we shall follow
our established policy of upping the tariff sharply for working on a set that shows definite evidence
of having been tampered with. As I have explained to you before, we do not do this with any idea of
'punishing' the owner for trying to do his own repair work. It is simply to pay us for the extra time
experience has shown will be necessary to repair and thoroughly check a receiver when a natural set
failure has been aggravated and complicated by untrained tinkering."
"Well," Barney said as he started for the service room, "since I have decided not to write that book,
perhaps I had better start doing a little work for that million."
"That's not a bad idea," Mac agreed as he followed him; "but if you really do want to make a lot
of money, I can give you an idea to be thinking about."
"I'm all ears; let's have it."
"Well, you start thinking of a good use to which you can put these TV towers after the necessity
for them has gone. As more and more TV stations come on the air and fringe areas cease to be fringe
areas, these towers are going to start coming down. Then a man will be able to pick them up, I figure,
just for dismantling them. Now if you can think of a really practical use to which you can put these
light, sturdy, long-lasting sections of tower, you will really be in business. About all I have come
up with so far are rose trellises and grape arbors; but I am sure that a sharp character like yourself,
with an imagination equal to that of Baron Munchausen, will be able to do much better than that."
"Um-m-m-m," Barney said as he pulled thoughtfully at an ear lobe, "I believe you've really got yourself
an idea there. For a while, of course, a guy could dismantle the towers in an area where a new TV station
started up and resell them in other fringe areas, but the sections are so bulky and hard to transport
that such a plan would not be very practical. I guess I'll have to dream up a really super on-the-spot
conversion for them."
"I'll be eagerly awaiting to hear about that," Mac promised as he switched on the bench lights and
picked up his solder gun.

Mac's Radio Service Shop Episodes on RF Cafe
This series of instructive stories was the brainchild of none other than John T.
Frye, creator of the Carl and Jerry series that ran in
Popular Electronics for many years. Mac's Radio Service Shop began life
in Radio & Television News
magazine (which itself started as simply Radio News), and then changed
its name to Mac's Service Shop after the magazine became
World. "Mac" is electronics repair shop owner Mac McGregor, and Barney
Jameson his his eager, if not somewhat naive, technician assistant. "Lessons" are
taught in story format with dialogs between Mac and Barney.
