They were over driven for three reasons.   The first was to make sure that the output didn't drop out and kill the oscillation at the high end of each band.   The second was to produce harmonics on the higher bands.   The third was to allow the unit to continue to operate as the tube aged. As far as the coils failing, some adsorbed moisture, which lowered their 'Q'.   Often, the 400 or 1,000 Hz tone was distorted, as well due to the lack of AGC. It gave a distinct sound in the receiver being aligned. Look at what HP did in their 606 and 608 series generators to produce a clean signal. They certainly didn't attempt to do it with two tubes!   I remember the low voltage tubes in car radios. They weren't used for very long. It was an attempt to eliminate the Vibrator derived HV plate supply, without using the more expensive transistors of their day. I think that Philco/Ford went that route, while Delco and Motorola went straight to all transistor designs. For used Philco, Bendix and Motorola radios in the '60s and '70a. BTW, Galvin Manufacturing invented the car radio, then they changed their name to Motorola to reflect their main product line.

Nice to know where that famous name came from, thanks!   https://en.wikipedia.org/wiki/Vehicle_audio speaks of a car radio in 1924 in NSW, Australia.     John :-#)#

Was it a real car radio, or a battery powered radio installed in a car? I also remember one of the old Roy Rogers TV show episodes with a battery powered radio on a horse that they used to catch the bad guys. I saw that over 50 years ago. ;-)   I remember when Bendix switched from TO-3 output transistors, to TO-220. Despite the warnings not to bend the leads at the case, they did. They had over a double digit failure rate within two months of the cars being sold. They used a tiny daughter board, and mounted it in one of the holes for the original package. They were very shitty radios. :(

I have a RCA 24 in my collection of early 20's radios that was an early luggable battery radio. Used a few WD-11s and had two spares in a holder - I imagine the tubes did not like being bounced around so spares were really needed!     > I remember when Bendix switched from TO-3 output transistors, to TO-220.

Imagine trying to get stable reception with a mobile positive feedback circuit set to the brink of oscillation, powered by either HT dry batteries or a vibrator PSU. Plus the thing had a huge aerial rig over the car. It wasn't a practical commercial proposition.   Of course you can lose the PFB and have a row of valves, but then your HT battery drain is far worse.     NT

Bipolars were developed in the '40s, but Field Effect were much earlier. They were unable to manufacture them, until the metalurgy improved to an acceptable level to do more that create single FETs in the lab.

millinghill@yahoo.com: May 15 12:51PM -0700 Hi, I'm a newbie here. My 14 year old broke our 75" Samsung LCD tv last week by slipping on a remote he didn't put away and hitting his head into it. The extended warranty doesn't cover a kid's head smashing into it. We saved for a long time to splurge on the $1,800 cost about 18months ago. Ouch. The glass is fine, but when you turn it on, the LCD is clearly and significantly shattered in the top left corner. Is there any Youtube video or other guidance on what parts to try to salvage (and resell on Ebay) before I just put this in a dumpster? If so, what's the possible resale in parts? Not worth it for, say, $50, but I would consider salvaging parts if possible to get more than that. Advice/Opinions appreciated. Thanks Theodore

Assuming LED backlights, shave the LEDs off the heatsink material with scalpel/blade,most will survive once you get the knack, for a lifetime supply of SM white LEDs for festoon lamp bodges or whatever.

abrsvc <dansabrservices@yahoo.com>: May 15 01:33PM -0700 Look up on Ebay using the model number off of the back. Get a feel for what most of the listings are asking for the boards. Add all the averages together and cut the total by say 25%. Post the entire set of boards and cables for that amount and see what happens. You can also start the "bidding" at 30% off of the lowered price and see where the competitive bidding gets up to as an option as well. In any case, the entire set should fit into a large flat rage USPS box (approx $13) which will make shipping easier for you too.   Dan
