    Lafayetts Telstat 140 SSB now just low power

    Were the driver and final original. or....???

    Carlbuilt 400HD vs C400 vs CM400

    Not from what I have seen. Horrible construction, the cheapest parts possible and oscillates like a kazoo, when driven below recommended limits. Spurs-a-plenty. But, he says, his amps don't spur. Must be some kind of voodoo in here that makes his junk special.

    Carlbuilt 400HD vs C400 vs CM400

    The bias he uses is class B schottky diodes and resistors. Garbage amps.

    Carlbuilt 400HD vs C400 vs CM400

    His bias circuit is crap. Schottky clamping diode/resistors

    unidentified module

    They also made their own with their name on them, as well as early 70's Realistic. They were high quality.

    6241 is Hitachi SSB

    unidentified module

    Carrier oscillator/clarifier from SSB Hitachi (maybe Sears), the connectors look very Hitachi to me. I have probably seen it before, but can't recall.

    Pll02A crystal info needed.

    There are methods to measure what you need, such as load capacitance. You need to learn how. Maybe, your Chinese crystal house knows how and is equipped to perform this. Send them the test samples from a working radio.

    Pll02A crystal info needed.

    I understand. You may need to pull the crystals from a working radio and test/measure.

    Pll02A crystal info needed.

    Now, it sounds as if you are not looking for one crystal, which is how I interpreted your post.

    Pll02A crystal info needed.

    Custom crystals are very expensive and limited to one vendor in the US. Their quality has been hit or miss for decades. If it was me, I would explore DDS VFO, not crystals.

    Lafayette Dyna-com 23 schematic

    I am in process of restoring one as well. I also had a bad speaker. I ordered 8 ohm 1 watt. If you look at the schematic, you can see the transformation, that I am going to workaround. I am also going to install an electret mic. Good luck with your project.

    Are you here to try to get help with the issue, or just to vent?
