Yesterday I received the last of parts I had on order to finish the Stereo-70 that I have been working on. The power supply was modified by adding radial lead electrolytics under the chassis for the first two sections that were originally in the can. The can is still there and being used, but the four sections were changed by paralleling two filter sections each for the two lowest B+ voltages. The new radials consisted of two 100mFd@350V each stacked and bridged by equalizing resistors. There is one set right after the rectifier tube and another after the choke for equivalent values of about 68mFd @ 600V or better. The OEM circuit board now has all new metal film resistors and polypropylene capacitors. The 10 ohm resistors in the input ground circuitry were all removed and replaced by wire jumpers. The OEM PC board was modified to use 6GH8A tubes as I had 51 of them on hand. New stainless steel chassis, output transformer for one channel and input jacks from DynakitParts.com took care of functional and cosmetic issues. The original chassis was too badly pitted and corroded to satisfy me or the wife. It is now a real piece of eye candy. Of course it sounds great. Bass response is much tighter and solid plus the sound stage, clarity and definition is much better than the 100W per channel solid state amp. that it replaces.
Thanks to everyone here for their help.
