Try the 25SN7, even cheaper than the 12SN7 the Brimar 13D1 been one of the best.
Do you know? Does the Brimar 13D1 sound significantly different than a Brimar 6SN7?

Hi rosgr63,
Shopping around for 12SN7 tubes I came across two other tubes that are supposed to be higher grade than the 12SN7 tubes for use in aircraft servo systems.
They are labeled 12SX7 and 2C52 and both are octal tubes. Would you know anything about them? Are they compatible with the 12SN7/6SN7 wiring, and is there any advantage using these tubes?
Hi chiman,
Instead of the 6N6P-i, spend a little extra money on a pair of 6N6P-IR tubes. Then, instead of the Mullard tubes, order a pair of the 6HM5 Yugoslavian Ei tubes for $10 best offer.
The total price should be the about the same or less, but the results will be better.

Good luck!
Hi mab1376,
From reading chiman's post I got the impression that he was just starting to do tube rolling, and that the tubes he picked required no modifications at all. I can well understand the hesitation and worry about using straps and adapters, so that's why I suggested something simple that is plug and play.
The 6AV6 tube is very good, but it requires switching to EF92 setting and cutting off and taping pins 5&6, and not everybody is comfortable in doing this.
As you well know, there are many driver tubes that are significantly better, but these tubes require modifications or adapters and voltage regulators.
I could see a market for an adapter package with a built in voltage regulator and different switches for using 6DJ8 wiring and 12AX7 wiring, as well as octal and loctal adapters (and a C3g adapter!).
