Selling this for a friend who has collected hifi gear for 50 years. Most of the hifi stuff I'm selling & sold is from him. More to list.
This preamp has been sitting idle for many years. I got it from him without any tubes so I'm selling with no tubes. I used my spares to test it.
I used a variac to bring it up, I got to about 50 VAC and sound came thru. I let it play at that voltage for about 1/2 hour. Between 70-80 VAC is noise but when I pushed to 110 VAC it sounded good and backed off. I only played with it for about an hour since I feared the old original electrolytic cans might fail. Unit looks to be all original with no repairs. One might be able to reform the can caps if you slowly increase VAC over a 2- or 3-day time period. Otherwise, a restoration should be done.
Faceplate has some wear and some speckles of rust, please check pictures, use zoom feature. The mode rotary switch was frozen so I used some WD40 and let it soak into the shaft for a little and now it moves but still a little hard to turn, needs to be worked some more.
I found this guy on you tube who gives a pretty through explanation of replacing the caps.
