Old Curtis Mathes Integrated Amp - Model HA230. I have no idea who actually made the guts for Curtis Mathes. Some have suggested it might have been NEC. I've not been able to find any manuals on line, and the company no longer exists.
Left = 24.4
Right = 26.1
About what I expected from what seems to be a rather "mid-fi" unit.
Another old integrated amp - a Kenwood KA1400G that I bought in 1975 as my first "decent" stereo equipment purchase. IIRC, it was $110 from a catalog company located in San Luis Obispo, CA. I had this worked over a couple years ago, but it's been doing 24/7/365 duty with a satellite radio receiver hooked up to it in the control room at work. It's back home now on the work bench, and the Curtis Mathes HA230 took it's place. I decided to bring it home because we thought the left channel was getting weak. I can't hear any audible difference here at home, so we must have been mistaken.
Left channel settled out at around 55.
The Right side settled out around 60.
The readings jumped around quite a bit, and I'll have to read more of this thread to see what that might mean. The numbers are not very good, so I might have to have it checked out again. Then again, maybe that's all I can expect out of a nearly 40 year old piece of equipment.
Interesting, and very long lived, thread.
