RCA Radiodyne 28
#29

BTW what did you get for a grid leak resistance, 8 to 8.2 megs is fine, much higher say 10 megs and volume may be too low...Or the detector will cut off and the radio will go Putt-putt sound.

#6 O.K. but the screws were #4, so long as there are no shorts...

That's a great technique, a little heat and the rosin gives way...

"We" are moving along, let me know as soon as you can if you need one of more of the large bypass caps and a volume rheostat cartridge.

BTW its O.K. for the bypasses on the B+ to leak a little as the ARBE-III can take the load... If it were battery's the leak would kill them...
