Myles, have you had a chance to hear the new Celestion G12 Century Vintage? I haven't heard much about this speaker. Thanks.

Myles, I read your review of the Ruby Tubes EL34B-STR and thought I might try either a pair of those or a pair of the GTKT66 HP's in this JTM45 type thing. I was thinking a #4 rating for the KT66's, but how does one specify an equivalent power rating for the Ruby tubes? I was planning on buying from Antique Electronic Supply who do some type of matching for $1 per tube.

Thanks, Myles. I appreciate your help.

Myles, I'm attempting to make a homemade JTM45 and have decided to do a DC filament supply for the 12AX7's. I'm using a couple extra diodes for voltage dropping. Anyway my question is that loaded with 3 12ax7's the filament voltage is 6.3 volts DC when the AC current is around 115-116 volts, at 120 volts the DC volts rise to around 6.6 volts. Do you think that's within an acceptable range (+ 5%)?
