Turret Booster Plug-In Amplifier |
||
Here is a bit of "outside-the-box" thinking from the vacuum tube era that is essentially a form of integrated circuit, where the active and passive components are discrete rather than semiconductor. The concept was to provide an assembly that could be plugged directly into a signal gain path tube socket and provide an additional amount of amplification without needing to do any special wiring or mounting of components to the chassis. The cost of $9.95 in 1951 is the equivalent of $99.99 in 2020 money, so it wasn't a cheap upgrade - and that did not include the cost of an additional tube (about another $10 in today's money). Given typical electronics service shop rates of just a couple bucks per hour in the early 1950s, it might have been cheaper to pay the local guy to do a customization of the circuit, and then tweak the operation of the entire television or radio set. Having high voltage connections exposed outside the metal chassis posed a serious electrocution potential (pun intended), and might have even made the set more susceptible to interference. These "Turret Booster" type gizmos were not found all throughout the electronics magazines, so my guess is they were not all they were cracked up to be. Turret Booster Plug-In Amplifier

About RF Cafe
Copyright: 1996 - 2024 Web BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
