Default Can anyone ID this amp? (there's no prize)

Hi

I've just been given this Crimson Electrik amp (see attached pics) but don't know if its any good, its age or even its output.

Can anyone help?

Thanks.

Still using the above - 1970 something CE1704 modules inside but you need to take the lid off to see which modules are fitted. These were a kit amp which cost very little but still sounds great. Marantz 6003cd, passive preamp crimson power amp and B&W 695 speakers.

The similar looking 2N3773 endowed CK1100 kit power amp was 100w per channel 8 ohm, 140w 4 ohm. The CK1100 had 4 smoothing caps and 2 chunky metal bridges to feed each module separately with +-50v but using the one mains transformer that looks much the same size as yours (the CK1100 transformer is 6" diameter). Your amp has 2N3055's so all in all, power may be a bit less. I seem to remember Crimson had a few 80w amps so this may be one of them.

about 40 watts rms into 8 ohm very low distortion midband about 0.01%
uses output triples a very nice amplifier
As made possibly in my home town of "stoke on trent"

The power amplifier is made a Crimson 40W +40W kit using the CE608 modules. The ones in this kit are issue 4 and were superseded in 1979. Crimson produced these type VII PCB which was much better particularly in the bass until 1999. The T03 devices were then replaced by plastic ones in the type VIII PCBs. Newer remanufactured PCBs are available. The electrolytic capacitors will need to be replaced due to aging. Some improvements in wiring and insulation needs doing to meet modern safety standards. The small PCB looks like a home brewed preamp supply.

Hi,

Looks much more like some form of added output protection
or switch on delay or both, it's not a preamp supply board.

rgds, sreten.

Crimson used to supply a PCB for that position as PSU for the preamp (Reg1), but I agree it looks like a protection/delay relay circuit.
