Adding A supply to this B Battery Eliminator
#8

Ah...thanks again! OK, trying to put together a parts list and what I need to order. Still have a few questions:

1.) What is LM317T, is that supposed to be a center tap choke? I see the 5K pot below it. If so, what value? Does AES have one that won't break the bank? (This was an $18.50 radio purchase! Icon_lol )

2.) I have a diode kit that has the IN4004 and IN4007, but they are super tiny. Do these go by number alone or are there higher amp I should be looking for?

3.) I may have a 10K mfd cap at 20 volts on hand. Would that work? for the 10 V winding?

4.) The two electrolytic caps on the 140 volt winding are both 47 mfd at 250V?

5.) The resistors, 240 ohm and 1000 ohm, would 1 watt be enough?

THANK YOU AGAIN! And no problem, Steve. I just wasn't following what you meant.
