I have a Audio Research Ref 5 main board that has had some damage and would be good for your own DIY Preamp project.
The board is in too rough of shape to be used in an ARC product but is easily modifiable for your own use. The board had a power supply capacitor fail which blew out the digital volume control chips. there is some trace damage around the power supply and the volume control chips have been removed. as well as the housekeeping transformer and output coupling caps (I have some we can talk about). For the buyer I can help with info and schematics.
Board uses a 6550/6H30 in the regulator section and 4x 6h30's for the preamp section. (I have some of those we can talk about also). You can use a standard volume control or use one of the MUSES volume control kits that have been advertised around here. they would sound better anyway!
You are buying a project. one that will take some crafting and work to get running. But once done, will sound EXCELLENT!!!
Asking $120 plus shipping. plus any extra parts you may want.
This is a LARGE board. Shipping in the USA is likely around $20-30 depending on where you are. shipping outside the USA will likely be expensive.
