    8.6 is the closest I have, I will go look for some. seems digi-key only has surface SMD

    Let me see if I have one. 9.6 on the dot?

    The base is at about 10.4V, the emitter at 9.7V and the collector at 13V. That all seems within reason...I think

    I wonder if the R310 at 470 ohms is failing. That is the 7.6V source, and it's at 9V?

    Yep, that drops the voltage, from 1 to 9 volts, and in between.

    Here is the channel selector cable that needs to be replace before going too much further.

    I think the VR you meant is VR107, I see it in the schematic, but not on the board...still looking. I see the point [4] is supposed to be at 7.9V as well, and that is the 9V I'm seeing. So I think it might need to have that 9V at reference [4] reduced somehow to the 7.9V.

    Adjusting the VR1 inline with the resistor and diode makes no difference

    Mixer IC I think

    I get it, I will check and see. I seem to lose the 10.24 at C119 a 22pf. I have it on one side closest to the pin1, but lose it on the other side. I pulled the diode and it shows 24pf...should I even be able to see it on the far side? Not sure all this RF stuff and signals work. It's all a...

    I wish I would have seen this before I started messing with this 611. Not the same really, but a good explanation of the Sardine Can. The one in this 1-641 has 2 more X-tals in it than the 611 version, but a good pre-requesite to get an understanding of what Royce does. He also has what looks...

    New addition to the family

    My niece has 2 of these, and 3 kids...the dogs out pace the kids on the energy level.

    OK, looking around a little more, I find that the Royce 619 shows a Sardine Can PLL that I think is very close to what I'm looking for. They call it an M2 U27 PLL, and that woke me up on what's happening. I'll upload a not very well scanned schematic of it. From this, the pin1 that I have...

    I have to get the channel selector back working and hooked up. The ribbon cable has the insulation peeling, actually more like cracking, off the wires and has no flexibility. I have some ribbon cable on way and it should be here today sometime. Hopefully it will be what I need, or at least allow...

    If you were a pirate broadcaster, what's playing right now?

    Some early Sammy, with Ronnie. Or if you have some time, and remember when they used to play albums on weekends...early 70's ROCK AND ROLL

    Another revelation, the 2002 is not the PLL. There is an IC under the X-tal I did not see that is a CCI3001. Now to start again getting readings from that IC. Regardless though, I still don't have the 1..24 at the CCI2001 Gets more confusing to me now. Pin1 of the 3001 has 18.205 and pin3 has...

    I took some voltage readings from the PLL. I don't seem to have the 9V on pin 10 as I should. Schematic has it getting it's 9V from the point [3] which is the regulator Q401, which I do have the 9V where it should be. Unless I'm missing something, I don't see where the 9V travels to the PLL. I...

    On the bottom of the sardine can on this unit are 14 pins, unlike the 24 in the previous diagram. On those, 3 and 8 have 6.47, and 9, 10, 12 have 12V. That's reading from the back of the board forward. Or the top down i the pic. I also took a voltage reading on Q401 (2SC1096), which is the...

    Channel Selector ribbon cable

    I went out into the garage to have a look around for my old cables. I think I may have had a moment of being tired of looking at all the junk I had and have laying around and tossed them. I have moments of just being frustrated trying to find things I know I have, and just filling the trash...

    Channel Selector ribbon cable

    Thanks, I did look at that as well. I get really confused with the metric measurements. Guess being taught in SAE most of my learning period in life, it's hard to grasp the whole metric thing. I don't know why we went to a European standard anyway, but that's another topic. For what I could...
