I am new to the forum and looking to solve a problem that has cropped up in my stereo system, and maybe you can lecture me on how to hook-up or trouble shoot systems.
I have owned a Carver M-400 since the mid-80's (does not have the polarized plug). For financial reasons I did not by a Carver pre-amp until recently. The M-400 has worked flawlessly since I bought it. I purchased the adapter that converted normal receiver signals to a pre-amp signal allowing me to control the M-400 through a normal receiver. And this is the way the system has been operated for years.
I recently purchased a used Carver C-11 pre-amp. I have hooked the entire system up but it periodically starts popping, with the amplifier LEDs jumping around. I have always shut the system down quickly and looked at my connections.
FYI, I have a Sony 300 disk player, a Philips CD recorder, Nakamichi Bx-100 cassette deck, and Infinity Rx-1 (?) speakers connected to the system.
While investigating this I found that the M-400 chassis, when connected to a ground, is carrying a lot of electrical current. This is probably not normal.
Has anyone here ran into this problem and what did they do about it? I suspect I will have to send the amplifier in for repair but am confused as to why the problem cropped up when I added the C-11 pre-amplifier.
I do not have the owners manual for the C-11, though it has been ordered, maybe it will tell me what I need to know.
Any help would be appreciated.
