So to be clear, by free I mean cover my costs and time, or I'll just take it to the skip.
All parts taken from a pair of Denon AVC A11SR amplifiers and AVC A10 SE; power rails for amplifiers are meant to be +/0/- 63V. quoted as 0.05%THD. Rated to 125w 6-16 ohm.
I have:
Power amplifier boards -
FROM 1st A11SR:
4 channel power amp board - should be fully working
3 channel power amp board - should be fully working. One cable from output to PSU had to be cut due to binded/cold welded screw.
Same again from 2nd amp except at least 2 possibly 3 channels have blown transistors from messing around.
A10SE power amplifiers are a single 5 channel strip, should be working fine.
All come mounted on heat sinks.
Power supplies - note some wires cut due to rounded screws, nothing a good bit of electrical engineering can't fix easily.
2 large linear boards from the A11SR's. oddly these have the video RCA connectors on the same PCB at the back!
One pair of caps is domed and should be replaced.
Main caps are 18000uF 71V 'Denon Audio' branded.
Have also removed smaller boards that supply DSPs/Pre amps etc
Toroids - rated at about 600VA (guessed from specs) shielded audio toroids. Note that this represents a tear down of what used to be £5000 in amplifier!
All power supply and amplifier boards in a single box for £50.
Toroids I'd rather keep, but I know I'm likely just to leave them in a drawer never to see daylight.
Add £30 for the AVC A10SE toroid.
Add £80 for BOTH of the AVC A11SRs toroids
