Does anyone know which tank was originally specified? I tried a 8BB2A1B which is the same tank as used in the RD100-112 and RD50-110, and it works pretty good, but not great. thanks in advance!   Mike Kaus (mm210) Username: mm210 Registered: 05-2006 Posted on Tuesday, September 20, 2011 - 09:47 am:    The only one that I have listed is the one in my list for "Music Man" of the accutonics chart that I had from SOMEWHERE. It lists a 4FB3D1B. Don't know if it's right though. The tank that came out of my 130 head is a 4FB3A1B. It looks like MM used a much higher impedance input than a lot of the Fender style tanks, that may be the difference. Your input impedance of THAT tank is lower than what your amp wants to see.

Will this matter if I know the 8bb2a1b works and has grounded in/outputs? in other words -will the insulated vs grounding matter? thanks again . . .   Mike Kaus (mm210) Username: mm210 Registered: 05-2006 Posted on Wednesday, September 21, 2011 - 08:02 am:    Should make any difference, I don't think.
