    Transformer for Tube Amp - Gold or Junk?

    We are dismantling an old production line at work, and one of the pieces of equipment had these neat transformers. They are step down to provide power to control circuits and motor power. They have a 600v primary and I was wondering if I could power the secondary with line voltage to use as a...

    Cobra 2000 GTL ideas...

    I didn't think that the stinger could do SSB? How about 70w for $26? https://www.amazon.com/dp/B0CJQJ1TLH?tag=worradfor-20

    Car Stereo Capacitors used for Amplifiers ?

    A second battery will outperform a big capacitor in a car stereo system. Unless you have a bank of super caps, it's just a waste of money. And I agree with @9C1Driver, a bigger alternator is the most practical solution.

    WANTED MOBILE $1,000W Export$ +-

    I almost forgot something about the 955. In the latest version, there is a provision to put a factory power board in it to increase the output to 100w if I remember correctly. There is a thread about it here somewhere, I will see if I can find it. Maybe @Greg T knows?

    Kenrich Eagle VIII

    It looks like a ferrite core out of a tuning can. Someone thought it would be equal to the resistor/wire wrap? I would be tempted to make it like the others.

    If you have two fans, you can wire them in series so they will only run half speed and they will be a lot quieter.

    WANTED MOBILE $1,000W Export$ +-

It is actually made by the company that makes the Anytone radios and has the noise reduction feature for tx and rx. It is basically a digital DSP filter that takes the...

    Home Ailunce HA1G GMRS HT Review - Retevis Giveaway Contest

    The radios have an IP67 rating which means that it can stay under water one meter deep for 30 minutes. This is convenient for people fishing or boating, although it doesn't float like some marine radios. The best part is that at the end of the day working in dusty conditions, you can wash the...

    Home Ailunce HA1G GMRS HT Review - Retevis Giveaway Contest

    The power measured at 4.2 watts on high and 0.5 watts on low. This is with my uncalibrated meter into a dummy load, so take it for what it is worth.
