It has 9 tubes. Three are 34's and six are 30's.
I will be making a power supply for it and it requires the following B voltages 0, +67.5, +135, and C voltages 0, -4.5, 7.5, -10, and 2 volts for the A supply. If you have any hint on making the power supply I will be most greatful. I was zeners for the 67.5 and 135 volt lines and 790X regulators for the negative lines.
Two of the 30's are a push pull class B amplifier. I called www.tubesandmore.com and they could not find it in ryders. I am betting that it is in there under a different name.
The radio has a filament control on the back of the radio. What is that for? My guess is that it is so you could connect the 6 volt tractor battery to the radio and use the pot to drop the voltage to 2 volts.
It has nine visible paper capacitors that I need to replace.
Thanks Paul
Look up Montgomery Wards Model 62-91 in Rider Vol #4, Montgomery Ward 4-4. It should be here on nostalgiaair under Rider schematics. Your actual model may be 62-41 since you were told it's a 41.
I will send you information on building a general power supply. You need to modify it for your radio. I would regulate the "A" section using a LM317 regulator.
The "C" section doesn't need regulation as little (no) current is drawn. Just use a resistor divider with cap to ground at each tap.
The "B" supply doesn't need regulation. Although your radio will draw current 20-30 ma from this supply exact voltage isn't critical. Try to keep voltages within 20%.

Thanks, It was the 62-41. I printed out the diagram. Now I need to take out my TV-7 A/U tube tester and check the tubes. Build a rubber part that went from the tuning shaft to the dial/condenser gang. Then recap. Build a Power Supply, tune it up and enjoy.
I guess that I will be done in a few weeks.
Take care,
Guido

How did the restoration go? I just picked up a wards airline superhet at a garage sale and just starting to look for info on it. the #'s on the label in the cabinet are Cat# 62-93 and a series # 07B from what i can tell, if anyone has any info that would help id appreciate it.
thank,
