Hi, Great web site! I've been playing through a Music Man amp since the late 70's. Thank you so much for providing a place where everybody can find all this great information about Music Man amps. I have a Music Man HD 130 reverb (with the 12AX7 tube) amp head. The original reverb tank has been replaced with another tank that really doesn't sound very good at all. I do have the original tank with one broken spring. I'd like to get it fixed and put back in my amp. I guess my question is.... What I have to do is find some replacement springs,(anybody know someone?) then find a tech to switch the tanks. Is there anything else I should be aware of? Just want to make sure I've got all the bases covered. Thank you for yor time. Best Regards, Dave | ||

Don't know where to get replacement springs but the tank itself has been replaced for yrs with an Accutronics tank. Look in this section for the right one for your amp. Mike. | ||

Thanks Mike, I'll give it a look. Dave | ||

Hi, I talked to a real nice fellow at Antique Electronic Supply. He has two reverb tanks that might fit my amp, one is a 150 ohm input and the other is a 1475 ohm input. Does anybody know which one is the right one? The one that was in my amp was a Accutronic 16 3/4" two spring tank.(I could not find a part number on it) The amp it was in is a Music Man HD130 Reverb Head with the 12AX7 tube. Thanks for any help you can give, Dave. | ||

I miswrote the above post, it's a question of which is the right input impedance for the amp. Can anybody help, I'll even take a good guess. I just want to get her back sounding like a Music Man amp. Thanks again for any help, Dave. | ||

I followed Ed Goforth's advice and installed a MOD 8BB3D1B long delay reverb tank in my MM RD50. It works much better with no hum, strong output, and more like the old Fender reverbs. I had to experiment and install a 45 dB L-pad to attenuate the return so the Reverb control would operate at "5" mid range on the knob. I mounted the passive pad in an old film canister.   | ||

The L-Pad should be plugged underneath the chassis in the return RCA jack. That way the signal stays strong until reaching the chassis thus less chance of picking up stray hum and noise. |
