I must admit that the larger amp would be awesome in my bedroom system, or any system that didn't require multi-channel output. In recently perusing various web sites, I saw not only a used Carver CM 1090, but the 150 Watt model above it. I never did buy (or miss) a tuner: as is the case now, radio was pretty much artistically bankrupt and useless. The CM 1090 was a very powerful and flexible component for the time. The CM 1090 possessed great power and dynamics, reproducing any type of music with strength and clarity.Īlthough it wasn't the first product to incorporate a motorized potentiometer, it was the first remote motorized volume I ever used, and this feature was a source of amazement and amusement for all my friends. The sonic holography was startling at times: often, while listening, I would turn with a start at a sound well behind or to the side of me. This was well before surround sound was prevelant. BRIDGE RECTIFIER D851 will handle the DC voltage polarity.I bought this piece back in the 80's.
Connect the output to the vacated holes where pins 2&4 (the secondary winding) of the BACKUP transformer were connected. but it may be several volts above or below the stated output voltage. If you choose the depraved route for testing the BACKUP remote control/standby circuit., check the polarity and output voltage before connection. It's only to be temporarily used for testing the BACKUP remote control/standby circuit. You can buy them on any street corner - they're everywhere. Something like this is plumbing the depths of depravity. This would supply the correct DC voltage for powering the remote control/standby circuit and RELAY RY851, but it may introduce unwanted noise in the audio amplifier circuitry. Both transformers should be set to the same working voltage. The MAIN transformer is protected by FUSE FU851, which should be removed. It also supplies power to RELAY RY851 which, when energised, provides power to the MAIN transformer. The BACKUP transformer supplies power to the remote control/standby circuit and is not fuse protected. This may be a PHYSICALLY suitable BACKUP transformer. * It's only partially modified because the BACKUP transformer wiring is currently undetermined, but was 120V. You should also disconnect/disable the rear convenience power outlets and label the equipment to show that it has been (partially *) modified for 240V operation. You should insulate the exposed joint between pins 4&5. Click to expand.Many thanks for the pictures.Ĭongratulations! The MAIN transformer appears to be correctly modified for 240V AC operation.
