Copland CSA 14 valve hybrid / solid state integrated amplifier + MM phonostage
Lovely clean unit with a few small tweaks :)
Hybrid in design in that the preamp section is vacuum tube and the output is solid state.
Runs at 60w per channel into 8 ohm.
Frequency response 5Hz - 120kKz
MM phono input which works well
Plenty on the web about these.
This is a very clean unit - see the photos.
Tweaks:
1) NOS US made, National branded 6922’s just dropped into the amp and rebiased correctly.
2) Opamps now Burson V5’s. Some say it makes no difference in the location used as it is not for gain, but I added them anyways.
3) Mains IEC fuse now a Create Audio Deluxe Series
4) Internal fuses now Aucharm silver alloy types
I have the original box but no manual. I will print of a copy of the service manual to be included.
£600 collected or £620 posted.
