Thanks Bayou, I will give it a shot in the mourning and test tr30 while I'm at it. I did test the voltages on it tr31 and tr15 also they were all good. I was thinking agc but the oscillator makes sense . Appreciate the help I'll post up the results once again Thanks Ira

P.S. I swapped out fl3 ssb filter with a known good one just because I wanted to eliminate it as a possible cause of swamping the agc.

This thing has had a full alignment works absolutely fantastic tx/rx spot on. But it does have one issue on ssb ? At full rf gain the audio has some distortion on it, back the rf gain down to six it clears right up spot on frequency. I've read some other post about this issue checked c43 10pf...

A friend got this thing for nothing 1x2x6 8950 tubes. So I cleaned it up best I could tested all the tubes bought Nomad radios hv supply board and the rest of the electrolytic caps, was going to put in the protection diodes on the cathode feed to the 2 drivers and the 6 finals and found a small...

Thanks Nomad it's reassuring to hear it from the guru. I was pretty sure that's the way it should be when switching to manual just wanted to make sure PO hadn't moved it, reverse engineering some of these mods is more time consuming then it should be dotting the i's crossing the t's. Appreciate...

Here's what I have Pin 1 anode of d128 to top lug clarifier. Pin 2- 3 blue/white , Pin 3 violet to anode of d125, pin 4-X, Pin 5-3 red/white, Pin 6-2 orange/white, Pin 7 Blank, Pin 8-X, Pin 9 Blank, Pin 10 orange, Pin 11 yellow, Pin 12-X. Everything is seems to be wired correctly radio...

Thanks Nomad, That's what I started with sure enough the crystal was bad was getting 23 mhz on the b and e of tr10 changed it out got 10.695 (odd see a lot of the legs ate up but rarely one that's gone high). Still had nothing to l18 and tr9 all the freqs were there just not getting through l18...

cobra 29xlr has receive, audio from pa, no tx output. Whats been done, aligned pll/vco per manual L5 peaked , 10.240 good stable, L20 3v stable, L21 peaked, L24 peaked at 37.878 (42-96) last 2 digits are oscillating? checked 36.570 at gate of tr18 spot on and stable, I think there should be 2...

P.S. I'm thinking IC5 going to check voltages on it.

Thanks again TM86 Mr. Dan had the Sam's issue I was looking for and sent it to me right away you guys are great. The Sam's issue shows the MA on both meters being the same just have to check if the face plate is removable. Once again Thank You So Much. Ira

Thank You so much Dan. Exactly what I needed Thanks Ira

Thanks TM86, just went there and posted. Trying to find out if the meters in the units are the same (1 MA) other than the face plate. My rx meter stays at full scale, it ohms open, my tx meter ohms at 1k, checked everything down stream from meter, zero pot adjusts and checks good as well as the...

Good morning Dan, would you happen to have Sam's photo fact #10, looking for the information on the Browning R27/S23 series radio. Thanks Ira

Just so everyone knows I found the R-27 schematic here https://oldtuberadio.com/data/Browning Labs/Browning R-27 sch.pdf still looking for the S-23. Anybody have a copy of Sam's photo fact #10 says it has the information on this series radio. Thanks Ira

Have the schematic and the owners manual. Trouble shooting the s-meter circuit stays full scale unit on and setup (rf gain max avc on) antenna disconnected, adjust zero pot no change in meter still full scale. The voltage does drop on the top lug yellow wire from adjusting the zero pot. Should...

Update (a little late with all these storms down here) The 1973 pre driver doesn't work in this configuration. Ordered the pre driver and a set of finals got them installed she came up to 6 watts a little more investigation found an issue with the ssb alc (bad ceramic cap) replaced that and she...

OK had a few minutes to hook up the old heath kit oscillator 10-32mhz added some modulation to produce a nice wave form injected it into the so239 started from there and moved thru the coils L28 to 31 and L33,34,35,37,41,38 and L39 also checked q47,48,49 and 51 base and emitter same wave form...
