Repaired failed power and driver amplifier stage stages. Replaced worn, exhausted axial electrolytic capacitors and some transistors in both channels. Tested and checked bias and idling currents. Receiving the amp back, I installed LEDs in the meter lights to replace the burnt-out originals. When I powered the amp up a few minutes later, the unit sparked and smoked, so back to the shop it went.
For the next six weeks, the amp was gone over with a fine-tooth comb to figure out what happened (FYI, it wasn't my LED job), repair what was damaged, and ensure there were no more small explosions. Outputs and drivers were replaced with modern-spec i. Higher quality and tolerance parts, some resistors were replaced, and I believe some capacitors were also replaced. After the repairs, the amp was tested extensively for about two or three weeks to make sure it is in tip-top shape. Everything is working great now.
Cosmetically, the amp looks great with a couple light scratches to the right of the right-hand meter and what look like teeth marks (tool, not human) on the left-hand fuse tray door. Ultra-sonically cleaned the knobs to bring them to a nice shine. Included is the original instruction manual, schematic, two lists of authorized service centres, and a list of details on and instructions for the FAN-1.
Use high-quality ECT48 double-walled box and lots of packing material (bubble wrap, peanuts, paper, styrofoam). I do not want anything happening to this monster.

Unfortunately, there are some not-so-honest people out there that claim additional damage, flaws, etc. For this reason, all items I sell are now as-is.Thank you for your understanding. Recently, courier companies UPS, etc. Have changed their rules for what they will and will not insure. The types of items not available for coverage include items deemed used and/or fragile, both of which describe this item. I want to insure, but for the previously described reason, it's either pointless or not possible.
But what if the parcel is lost? Thats one trick couriers pull. I cannot respond to them that way.Use the Best Offer portal. And please do not ask me what my lowest price is.
Messages asking for my lowest/best price will be ignored. Do not ask for a discount. And I will find you the lowest cost courier quote.Any questions, feel free to ask! _gsrx_vers_1292 GS 8.3.6 (1292).
