looking to trade or sell an elkin 8 tube and possibly 2 elkin 4 tube amps. looking to get out of some older stuff and into some newer stuff as far as amps go. will consider trades for different base/mobile low or high drive good made transistor type amps. also am looking for a really good first...

just got one of these from fleabay. no transmit but it does have receive. anyone worked on one of these and no some of the common problems? so far it looks like there should be 8volts? going to the main RF board and there isn't. it has been soldered here and there but the relay kicks in on...

I have a few MB3756 voltage regulators for older Cobra 148gtl and Uniden Grants etc. If anyone is interested they will be $6.50 plus shipping. These are new and I will bench test every one I ship. I started a new thread because I put the wrong price on previous.:blushing: paypal only please...

I have a Taiwan 148 gtl that I have replaced several caps in. I now have about 3/4 of a watt carrier with about 5 watts swing. I have looked at all kinds of voltages and seem to be stumped at whats causing the low carrier. On SSB it will do about 13 watts max (all watts PEP) with the limiter...

Just got a 29xlr and it powers up but no receive or transmit. have chased my tail on it for several hours now, replaced several caps and attempted to trace voltages to no avail. Anyone know what the test point voltages should be in this rig or any ideas of common problems, Thanks

I have a early 80 model 148gtl, on AM with mic gain turned all the way down it will only dead key 3/4 of a watt but when the mic gain is turned up it squeals to a constant 2 watts no matter how high the carrier is set. PA function works but it squeals with just the mic gain cracked open. was...

anybody know what is a good starting point or recommendation for the 1969 and 2312 driver and final bias. I have read different voltage settings and amp settings all for a 148 GTL.

got a 148nw with overheated am regulator. changing that and now or always the ssb is muffled and you can't make out what you're saying. the AM has good carrier and modest swing. any ideas what is making the sideband so low? There is also a hot spot on the board at L501, C501 and I assume R501...
