Ok, got the 8 tube GTO today. Everything looks great other than the center holes of both SO239's are wallered out big time. User got rid of due to not keying up anymore. He said he was talking on it and heard an arc around the rear corner and it smelt like electrical arc, then it wouldn't key...

You are looking at the last big amp Screwdriver (here in NC) ever built due to his health has left him unable to do it anymore. Turbo Smasher 1 tube - 3CX400A Max input key - 50w Max input swing - 50w Max output key - 500w Max output swing - 1700w Large squirrel fan

Hi all, been away for a while and in the process I lost my login info. Thanks to CableGuy and AuduoShockWave for getting me back up. I truly appreciate you guys. Today we have a Mark 8 (8 Tube - 17DQ6B) amplifier on the desk. Yes, I'm now starting to do little repairs on these, although I don't...

Got a different Galaxy DX 2517 on the desk today showing the same symptom as the last 2517. Symptom: Low receive (sensitivity and volume) in all modes. Everything else works as it should. Transmit is around 50w PEP (SSB around 35w). I've already checked the usual, Switches Controls Wires Wire...

Well, i just diffused the green meter lights in my Saturn because there was a bright spot in the center of the meters and the light wasn't spreading uniform across the meter. 180 grit sandpaper. Sand down the tip of your LED bulb. Wipe off the shavings from sanding. Put bulb back in. World...

Hi all, Got a question for all those out here that work on other people's radio equipment (can't call them TECHS, the college degree holders may get offended): After you're done with a radio and it works perfect, then you get it to the owner only for them to experience strange noises or...

Got a question about these export radios with frequency counters, specifically the EPT style counters. Is there a list of which frequency counters work in which radios? Example: I had a friend's 2980 on the desk a year or so ago and the frequency display was blank. Well I took mine out of my...

I've been looking into these Schottkey diodes/transistors for receive/NB improvement. I've learned there's many different types of specific diodes and transistors you can use. I've heard differing opinions on the "improvement" diodes/transistors and wanted a little more info on the different...

Got another Galaxy Saturn on the desk today. Issue: Keeps blowing finals. Evaluation: Passthrough regulator is fine. AF regulator is fine. Pre-driver is fine. Driver is fine. Replaced both finals with good ones. No swing mods. Output caps test as good. All traces have firm joints. Bias diodes...

Got another Saturn on the desk. The issue is low receive (it's got receive but just a little low). Evaluation: All the electrolytic caps were either high esr, shorted or dried up. Everything else looks great. Replaced all electrolytic caps with new ones. After: Receive came up some but not...

Got a question on the CTCSS function of the Retevis HS4. Is there anyway to lock onto someone's code they have set on their end? I've heard that if I go to a frequency in FM mode that someone has a code set on, but I don't have the code for, that I could go into the menu and move to the...

Got a Colt Excalibur on the desk today. Nice looking radio, eat up with roach tracks and crap. Cleaned it out thoroughly. Radio comes on but has very low volume on receive (signals are very good on meter though) even with volume wide open (barely hear it). Tried to transmit and it just makes a...

Got a Sears RoadTalker 40 base on the desk today. Issue: Powers on and that's it. Very little hiss in speaker with volume wide open. No transmit. Meter light out. Evaluation: Needs recapping throughout. No hackery anywhere in this radio. Got the receive and transmit issue fixed. Turned out to...

I had went through all my finals/drivers the other day with my tester (TC1) three times each. All these transistors showed as good transistors with good HFe. The NOS Mitsubishi 1969's I had checked and showed as 40 to 75, now show as 0 to 2 HFe. The NOS 2312's showed over 50, now show 0 to 2...

Got another Galaxy Saturn on the desk today. Someone stamped the sale date on the inside heat shield. Sell date was July of 1996. Issue: Low transmit power. Evaluation: Tested finals, driver, pre-driver, af regulator, Passthrough regulator, solder joints. All check out good, except for the...

Got an old Cobra 142 GTL on the desk today. Issue: Low transmit in all modes. This radio belongs to a local that I talk to on a daily basis. He talked on this radio for about 6 months after he got it back from me. I just recapped it and aligned it. It was doing around 18w in all modes and AM...

Got a question... There's a local around here that speaks often about his radio having two separate controls mounted on the back of his radio. He states one is to vary is RMS, while the other varies his Peak. He had it done by a well known radio guy down south of me (very well known in the...

Got a Cobra 148GTL on the desk today. Owner just wanted a checkup. No channel mods No clarifier mods Limiter(s) intact No swing mods Only mod is a variable key on the back of the chassis (they removed the AM power VR and wired an external potentiometer in its place). Wax still in VCO, xmit...

Got a Cherokee CBS-1000 on the desk tonight. Looks like it went through a metal shredder, lol... Cover is all mangled up and marked up. Evaluation: Carrier level too high (6w carrier). Limiter removed. Audio IC getting hot. Off frequency. Audio sensitivity down (receive and transmit). Power...

Got another Galaxy DX 55V on the desk. Been tracking this issue down for about 3 weeks now. New driver New final New pre-driver New Passthrough regulator New AF regulator New diode at D77 New 2.2uf 50v bias cap Both 22uh inductors new When keying, radio will switch from receive to transmit...
