New Price: Full Sugden Masterclass SPA-4 Class-A Amp Kit PCB and all parts
For Sale complete Sugden Masterclass SPA-4 Kit, including:
-Two SU9716 PCB, Sugden Masterclass SPA-4 amplifier PCB with all the parts (Sanken 2SC2922 and 2SA1216 output transistors)
-Additional SU9801 Speaker Protection PCB (includes the +/-18V supply needed for both input PCB).
-Additional SU9802 (L) & SU9803 (R) Balance Stage PCB, Single Ended and Balanced Inputs (with SE/BAL Converter).
-Special Mica insulators for the amp Sanken transistors MT-200 pack (39x24mm)...
-Includes all docs, schematics, detailled BOM, PCB silkscreen for assembly and test.
The amp uses a pair of Sanken 2SC2922 and 2SA1216 output transistors, a DC servo.
The Speaker protection and input PCB were done by me, using the original Sugden schematics. They are fully functionnal and tested.
The Two amp PCB were partially tested with current limited +/-35V supplies, and no heatsink. So final full bias test (900ma according to schematic) needs to be done on appropriate heatsinks...
So you have all the needed parts to build complete Sugden Masterclass SPA-4 Amplifier, just need to add the +/-35V supplies, connectors and an enclosure with heatsink...
I bought the two amp pcb from an other member years ago, private sale.
I made the missing pcb (input and protection) to complete the amp myself.
Schematics available on request...
Asking price is less than cost of parts (more than 550U$ + shipping). Just have to many projects, this one needs to go. My loss, your gain...
Asking price 400U$ (Or best offer) + shipping + Paypal 3.5%
