And their not hard to find or to expensive for nos. Out of the big box of tubes, and some are quite rare by today’s standards, a humble Sylvania 12AT7 ended up giving consistently best results.

The tubes at the other end of this list tended to have smaller plates.

Some say it has little or no effect while others claim it’s critical to have a high quality 12AT7 in this slot. The Philips is a touch quieter, and seems to take a little of that “doink” sound out of it.

The older ’60s Mullard don’t have the full lows that the later-production ones do, and neither do any of the other NOS 12AT7 or I’ve tried including 3-mica Sylvania and GE -they’re noticeably more bright and dry.

Each will give reduced gain and a different tone. This tube gives me the quintessential reverb tone I’d personally prefer: V5 This is the least critical tube position in your amp.

Do you already have an account? Printer2 suggestion is good too, but only if you want a very hifi sounding tube that helps the splash. However, for the reverb driver, you’re fir looking for a lo-fi driver tube meant to be punished. Most amps use either a 12AX7 or 12AT7 for this purpose. This is used as an oscillator for the tremolo circuit and has absolutely no effect on tone. You can also opt to remove this tube entirely. Makes the reverb more realistic for me. Andy BJul 30,
