I have a 700B that I have had Louisville Magnetic Tape work the bugs out. I got it running from some help from you guys and the forum. I am wanting to compare it to a WOPL700B. I also have a Mcintosh 7270. Anyone around Louisville Area that would be interested in a "test"?

Order 4 to have spares. Thanks to all!

19 weeks factory lead times. Not sure what the HUH means but I don't want to wait 19 weeks.

Thoughts about these on eBay...

Well I was going to order and replace the pot asap but they are 19 weeks out. In a quick search I only found quants of 300+. An other places or recommendation on the potentiometers? I can easily ( as old electronics go) remove and replace but I want to make sure I get the right ones.

Funny. I only took about 5 minutes of excercising to figure it out. I need a new pot! It is really bad now. Any recommendations for replacement pots?

Should I excersie the pot with power on it or no power? It precious had zero effect when I had adjusted it, but never for 20 minutes. Just a time or two. I will exercise it for sure.

Ok, I am loving my original PL700B. I had to take it to a shop in louisville to work the bugs out. It had been running well for many hours, but..... I now have a scratchy noise on the left channel. I have switch everything an been able to isolate it to the left channel of the amp! It is only...

I had a chance to check that my RCA's are passing signal. I check with the unit powered on that I have power at the fuses and 200 VDC on the transistor rails. Is that correct. I have check al transitions (in the chase) and test out ok doing a diode test from DC voltage drop. When I check the...

Easy enough. I will check with RCA wires plugged in to night and let you know what I find. Finger crossed its that easy. Maybe, I haven't found any other issues, but seems weird that it would fail while sitting still.

Thank you all for your feedback and all info and offers. I haven't checked the spring inside the RCA jacks (didn't know it was there). What is the best way to check the RCA jack to make sure that it is indeed pass the signal?

WOPL Sniffer. I not really sure how to respond, but thanks for you help and info. I had a PL 400 and loved it. It was my first real hifi amp. While it wasn't really audiophile quality it was close enough for me. I have restarted my two channel hobby after 20 years and I have this Phase Linear...

Thanks for your response and yes I miss spoke. I recently purchase the output protection relay circuit from you and new power caps from white oak. I like to start with a good baseline and I am never afraid to fix something. That said I am a car guy. I can wire a house or a garage, but circuits...
