You're wrong. 8ufd in series with 1000ufd isn't going to change anything. What's more important is that the 8ufd ground return will not be going through the 100ohm resistor. And the 8ufd caps will be on the correct polarity side of the 1000ufd cap. Look at the schematic.
Probably will not make much difference but if I was building that supply I would ground the 8ufd caps at the chassis ground point. The bias supply works from chassis ground and that's where the caps should be grounded.
Just because the xmtr was design that way doesn't always mean it's right. Especially, a xmtr with so many hum problems. That in itself should tell you something, like how many other errors are in the design. The use of the high pass filter to reduce the hum problems the xmtr has is another indication of design issues.
This is my last post on this subject, done finito! ! ! ! You have A testa doro! !
1. that thing was designed by someone that knew more than either of us! And it was designed for a specific purpose. (which they did well) They were also designed to be able to be operated by some one with minimal knowledge of radio theory.
2. de-emphasizing the audio bandwidth was a very popular way to 1. eliminate noise monsters, and 2. "increase talk power" back in those days. It put the max volume right in the middle voice frequency range. (why waste mod power and final dissapation on frequencies that dont help your cause) and 3. minimise bandwidth.
3. the Hi-FI conversions are OUR thing, because we want to sound good and sound natural. Most, if not all military rigs with carbonium microphoniums are designed to sound like you have a clothespin on your nose.
Power supply filtering is always supposed to be on the rectifier output, period. Between + and - short, sweet, and simple. Holding the initial
filtering above one side with a resistor is inviting a ripple issue. After the initial filtering you can do what you want with either side and voltage dividers, etc. But I have never seen any kind of power supply that had any resistance between one end of the initial filter and the rectifier outpoot.Done, over, last post! I know you will want the last word!
