Hello, I have a Music Man 210-HD 130 with the 2275-130 chassis. I live in Asia and want to have the caps all replaced. First of all does anyone have a list of all the caps I need to buy? I would like to get the parts and then find someone to install them. I want to replace all the caps and any other necessary things while it is being serviced since it is easier while it is apart. Secondly I would like to change the power from 110v to 220v. A friend of mine said the power transformer might be switchable where the wires could be switched to do this. Does anyone know if that is possible or must I buy another power transformer and where can I buy that. Thank you for any information. Gibs | ||

Hi Gibs, does the amp have the 12AX7 (ECC83) phase splitter tube? The component list will be different depending on which version you have. If you power transformer is not of the EX type, it needs to be exchanged. Sincerely Lars Verholt | ||

As Lars stated(and he's ALWAYS right!) they are different animals. Let us know exactly what amp you have and we can put together a list. You CAN look at the schem on this site and count them up if you want to do it yourself. If not, we can. I have a 130 watt chassis out that I use for picture taking if you need any shots for comparison. | ||

Mike, you need to talk to my wife - she thinks, well, the opposite of you 8-) Just checked Tubeampdoctor.com - they stock 220V power transformers. As far as I can tell the transformers are sold 'naked' without covers. Can any of our esteemed members share information or experience with the TAD replacement transformers? Cheers, Lars Verholt | ||

Hi, Sorry it took so long to reply. I thought this board would email me when there is a reply. It never happened and I had to really search to find my own post. Anyway yes it does have a 12AX7 tube. Not sure about the power supply until I get it taken apart. I am waiting on a friend but he is busy now. I don't want to do this project myself. It scares me a bit. If you could provide me a list of components to replace I would greatly appreciate it. Thanks again, Gibs | ||

4-150uF@50v 1-100uF@100v 1-50@50v 2-100uF@450v 2-20uF@450v That's IF you replace the two on the main circuit board AND the bias supply board(very important) | ||

Mike, Thanks for the list. I appreciate it. One more thing what type of termination are those caps? Thanks, Gibs | ||

They are all axial. | ||
