    I’m new to radio restoration. I have a 1941 silvertone 2511 (ch 101.650) as a project. I wanted to test the tubes but my tube tester ( superior TV-12) does not have the tubes listed. for example It has 1A5 listed but not 1A5G. Can I use the 1A5 setting to check the 1A5G. There are other tubes like that

    Hi – yes you can use those settings – There are tons of websites including this one that deal with radio restoration – for tube substitions you can use Nostalgia Air’s resource section – there are others –
    Just about anything can be found online these days – Google "tube substitution guide" – or "tube essential characteristics" etc. Many of the radio forums have a search function where you can search previous discussion threads – if you want hard copy info – then search out a club near you and attend meetings and auctions – there’s a ton of stuff available – especially now – its easier to get stuff now than its ever been – good luck.

    I believe the "G" in 1A5G denotes glass envelope. Identical electrical characteristics to 1A5.

    My favorite tube characteristics website is Easy to use and lists just about every tube you’ll ever come across.
