First off Merry Christmas to ALL...Yes I do have the same amp. I swaped the rectifier tube that was in it for a 5Y3GT tube and that seemed to lower the voltages some and stoped the red plating . Also I had mine hooked up to a variac running at 118 volts.Somewhere I thought their was a schmatic...

Sansui Photo, If your service service manual showes this board yes I would like a scan of it if possible thanks PM sent. steve

Went down to the basement last night armed with the the procedure paper work to ajust the bias and dc offset on my 771 receiver, things went well and so I moved on to replacing the stereo indicator bulb. Found a replacement and hooked it up and still no light. On outher receivers there is a...

Thank you for guilding me to the info that I needed, I looked in the data base but wasnt smart enough to see that their were more than one page to it, seemed kinda strange to me. I was looking at it last night and I didnt notice any of those wonderful fusesistors in it, A little trial and error...

I pick this receiver up a few weeks ago with some receiving issures so the seller said, Using a pair of head phones I started checking it out, reception was poor all up and down the FM band. This receiver has a open tuning cap so I got some cleaner and cleaned the contacts and put a drop of...

The owner saye he has rotated the woofer and it does correct the problem for a short peorid but returns . englissa

I'm also gunshy about the rubbing voice coil, have they been overpowered ? the owner says they feel smooth when pushed by hand. Maybe spider getting weak. Replacing the spider is something beyond my skill level, refoam yes, spider no. I dont want to do a total rebuild on these's englissa

I'm looking for quality and the sound, in the pecking order of speakers can I assume their fair to decent sound ? I have the feeling that theses arnt the highly sought after ones englissa

These's came up on Deleware craigslist and I'm thinking about getting them, talked to the owner and he say's one of the woofers have voice coil rub. Thoughts and opions ? englissa http://delaware.craigslist.org/ele/1760880489.html

Gentlemen I thank you for your advise, I'm convinced the CD spin motor is bad and I picked up another CD player same make and model that does work for a few bucks so this one goes to the trash. steve
