Vintage Tube Amp

1975 Music Man HD-130. Electric Guitar Amplifier Head. It had been used quite a bit by a previous owner who painted some hardware and Tolex black, red on the handle ends, and blue on the logo and badges. The amp was still in good shape and had the original giant rubber sliders and all 8 corners so I bought it and added it right to my collection in the early 1990′s. There is a modification of two holes drilled into back of the chassis in-between the back plates; we cannot figure out what they were for. (Please see photos) This amp comes with it’s original cover and reverb tank. Recently (Nov 2024) I took it to my current amp tech and he replaced the filter caps, added 4 new 1/2 longer chassis mounting bolts, lubricated the pots and switches, powered it for an hour and checked operation. He says it’s now in great shape and is very loud. This is a 130 watt amp. Serial # B 000472. Cabinet Yellow Marker Stamp. (13th week of 1975). (38th week of 1973). (14th week of 1975). It might serve the buyers purpose to bring up the power slowly with a variac since these used amp heads are over 50 years old and have not been used for a few decades. Our amp tech has only replaced the needed parts -(filter caps & power cords as specified) to just get them turned on and running for an hour. Please see a skilled amp tech before extended use. The operation of the amps requires that they be regularly serviced for optimal performance. Please remember these are vintage pieces, we cannot guarantee that they will not need service or more parts in their future; only some obvious parts were changed to get it working. Most of the parts are still the original old parts remaining which will be stated in our listings. We do not have any control on what was done by previous owners, but we try to write in detail any information we have.
