    Modern Brimar tubes

    A simple search on Google shows up the UK Brimar website selling modern Brimar tubes. I know vintage Brimar 12au7 is a good alternative to Millard and maybe Telefunken ones, but what about modern Brimars? Do modern Brimar tubes live up to their glories in the past?

    A question about biasing new tubes

    Hi all, I just replaced seven year old Svetlana EL34 tubes (one of the tubes shorted) with Mullard re-issues. When I hooked up the new tubes and let the amp warm up (twenty minutes) I hooked up my multi-meter. The previous older tubes had the bias set to 1.56 (dynaco specifications) but when I...

    12ax7 tube rolling Fisher 500b

    I'd restored the 500B some time ago. Jim McShane Kit with PIO K40Ys and Matched Tung Sol quad from him also + IBBA. Decided to order a set of the Sovtek 12AX7LPS and got here this afternoon. After taking out the 7 12AX7s in the chassis, I found they all measured ~56 on my Eico 625. The New...

    Bootstrapped Mullard 5-20-style front end

    Spent some time tonight fiddling around with my idea for a bootstrapped Mullard 5-20-style front end (AF gain + inverter stages) for a 6550 U-L amp. The simulation behaved more or less exactly as I expected it to (modulo my triode models not liking a CCS in the inverter tail for whatever...

    Altec Lansing 345a w/ Mullard EL34 and Scott 222-B w/ Telefunken 12ax7

    I recently acquired several older amplifiers from a former hobbyist cleaning out their stash of stuff they never use. A few of the pieces are pretty interesting. One is a Scott 222-B integrated amp that is in really nice condition. The other is an Altec Lansing 345A. Additionally, there were two...
