    First PL700 Check Out

    Yeah, I can appreciate that, it is kind of random. The problem I had initially was a bad output transistor on the right channel. I replaced it and then when I got to setting bias, the left channel seemed to set fine and the right was 0 volts if I remember correctly. Let me go check back in this...

    They were made on diode range

    First PL700 Check Out

    Maybe I should take you up on shotgunning this. I wish I had made some troubleshooting progress but I haven't. I'm back in town for a couple weeks and will take some time to maybe start removing components and testing them out of circuit. Thanks all again

    First PL700 Check Out

    It's a neat collection for sure just have to get them up and running. So here's the next 2 pages. You may be able to read my poor notes but C8 and C9 seemed out of place. Thinking I was on to something I removed them and checked with the little LC1 tester. You can see the results next to them...

    First PL700 Check Out

    So home for a little bit before I have to head out again tomorrow. The pic is of my progress sheet in comparing the right and left channels. Q5 showed substantially different values across pin1 and 2 as per my numeration process. I removed it and checked it with a transistor tester and it was...

    First PL700 Check Out

    This is a HOOT. I am going to do some kind of spreadsheet or graph or hieroglyphics of some sort to keep track as Don suggested and check both sides once again. I will name them as I check them, not like Sam or Cliff but by their given names. That way at least I'll be learning their locations...

    First PL700 Check Out

    Gotcha, I will do as you suggest. I did change Q10 to the same that had been installed previously. It tested ok after I removed it but I had purchased some new ones so I changed it anyway. I understand about putting the correct components back in instead of these other ones. I was hoping I could...

    First PL700 Check Out

    Well, not making any appreciable progress. I appreciate the help though I've been unable to put it to much good use. I will run through again and see what I missed.

    First PL700 Check Out

    I pulled one end of R3 out because I still measured the 1.8 across the points for C1 even with it removed. R3 tested very close to the 39k it's spec'd. Still checking.

    I went ahead and pulled C1 out and tested it with my little TC1 and it shows 109pf I assume that's fine?

    First PL700 Check Out

    Double checking and I found C1 on the right shows 1.7 in one direction and 1.8 in the other. It shows infinity on the left channel.

    First PL700 Check Out

    Q8 & 9 are still in the left channel, was I supposed to remove them as well? Sorry for the maybe simple questions.

    First PL700 Check Out

    Not seeing a lot of differences checking the components side to side with the fuses removed and power off excepting the diodes 6, 7 and 8. On the right channel I am getting about .62 volts one way and 1.3 the other. On the left I am getting the .62 but the other way I am about 1.8. No idea if...

    Copy that, thank you

    First PL700 Check Out

    Alright, so back at it, been working some which is a nice change. So right channel Q8&9 pulled. Still only .5 volts and thousandths on Q10 as described above. So to check the diodes do I need to take them out of circuit? Checking the voltages through D6, 7 & 8 they are not anything like the ones...
