These are pictures I wanted to show. The first one is the NR board that Les said he had never seen. The second pic is showing 2 3w power resistors totaling 1590 ohms. According to the schematic there should be an 820 ohm resistor there. I will show the S/N of the unit and the schematic where it's showing the values of the resistors for High efficiency power regulator that Les is selling. I was able to locate another SP 508 board on E bay all intact.

How do you post pictures on here?

Hi All! New kid on the block. I have an MRX 130 receiver and a Nakamichi BX300 cassette deck along with a Nakamichi CD player. I also have a B&O RX turntable. I finally got them out of storage after 15yrs or so. Needless to say all this equipment had issues, had to replace belts on everything, but I'm having some issues with the Receiver. I've been in touch with Les Wolff and purchased new relays, also got the high efficiency power regulator, however my NR board looks nothing like his example and my other resistors don't have all the same values. I can't post my pictures of said devices due to site rules so we'll just have to wait this one out! This Receiver has never been in a shop and I am the original owner. I showed the picture to Les and said he's never seen that version before. I'm guessing it's a very early design if he hasn't sen it before. I would like to know if any of the other Gurus on this site have seen this version before. If I can say anything about it that's different the color of the board is Green and there far less components on the board. I may have shot myself in the foot, by not taking my time with removing output relays. What I'm saying is that I didn't remove enough solder and forcibly removed the relay and pulled part of 2 traces off with it. Does anyone know if I can get an SP 508 board to replace it ? I can probably repair it for now but then it would less than perfect! I'm all ears.
