Gentlemen:

Will anyone trade a new 6E5 "eye" tube with a straight glass envelope for a new 6E5 "eye" tube with the shouldered glass envelope? My Silvertone actually uses the shoulder as part of the indicator support.

Thanks
Lou

A NOS ST 6E5 will be hard to find. Very early ones were ST shape. Most replacements were made with straight sides.

There are ST 6N5's around. This is like a 6AB5 but ST instead of straight. Only for used in parallel wired filament radios.

Only other tube would be 6G5 but like 6E5 hard to find. Replacements were straight sided and called 6U5/6G5.

I actually have a NEW 6G5 with the ST shape, but the substitution guide said "may not work in all circuits". Should I worry about it or wait and be a purist??

6G5 works but will have less eye movement. 6G5 takes -22 volts AVC to close. 6E5 needs -8 volts. Might be able to make changes and get more negative AVC voltage?

Changes? I'd rather cut off my arm than modify a radio!!! I'd probably default to the straight 6E5.

I ran into the same problem a few years back. An Airline Miracle had a 6AB5 which is strait, but the frame was designed to hold the ST shaped 6N5. It took advantage of the wide part of the ST glass to hold the tube in place. I suspect you have the same arrangement.

The tube was original with the set, and taped in with black electrical tape.

Oddly the 6E5 was built as ST and strait. Both types had the same part number, causing confusion in tthe electronics industry. They didn't make that mistake again as far as I know.

Best Regards,
