News is NOT what the host or newsreader says or thinks it is about what the guest or newsmaker says or thinks. Go to drudge in the morning and find the facts for yourself. The stories there will be on every station for at least 24 hours. Think for your self sheepole... LOL -Allen

I checked the collector voltage on the driver and final and I have only +3VDC in AM transmit. 13.xx in SSB. Should be 5.4 VDC I think. Any ideas ? TIA -Allen

Well I have taken a break and I am working on a 148GTL which isn't as modified. I did pull a few possible bad parts to check or replace. TR 40 2sc496. was good. TR 38 2sc1973 was good. I replaced a few caps that might have caused issues with higher voltage ones. I had one oddball that was a...

Grinder you can do quite a lot with minimal equipment. I multimeter is under 20 bucks which you can use for car and home repairs as well as electronics. An inexpensive soldering pencil and some solder also very inexpensive. Your eyeballs... That is most often all you need. Of course some decent...

At the base of TR38 I get a nice waveform but it seems to be folded over and is all negative going and about .2 volts I pulled it and checked it and it tested good. IC6 SO42P is the source I will check those in and out and see if it is bad. -Allen

Back on the old 142gtl I removed the crystal switch mod. I put the L37 and 38 back to their proper places. I touched up a few shady solder joints. I checked the regulator it seemed odd to me as it checked 489 and 508 on the diode setting... two legs lifted I have seen them a few off like 509...

WooHoo I got another one ( Ebay Treasure ) 44 bucks works good and unmolested. I have a "go by" now LOL. other than a hum is rx and tx fine 3-4 wats out in AM. Listening to LA right now. -Allen

Hey Thanks , I had read those posts of yours here and on other forums. Still that MV12YH seems pretty mysterious doesn't it? I have my bench DVM and scope setup now and my generator I just got on the 24th.. So I did poke around on it yesterday briefly. I am leaning toward there being no...

Thanks I got two mounted diodes( MVXX) disconnected to check. My schematic called it out as D46??? I'll see if I have an export schematic or DX model that is different. Anyway I took two diodes off a circuit board in my junk bin. and tested them separately they check good. Connected together...

D-47 checked BAD I think it checked 0L on the diode setting. I read your post about subs to check to see if it restores bias control that help TY MV-13-YH -Allen

VR9 TP7 I get 45Ma VR8 TP8 I get 40Ma the pot is maxed out, the Sams you pointed me to says 35 Ma. I rechecked B+ and turned it up a tad to 13.8 which the sam's called for also. I changed meters to do this. I thought maybe the other one was bad ( probably was ) Still good modulation but still no...

D49 and D49 checked good. I looked at the SK-3054( apparently replaced in my 142) which you say NTE-152 is a better part NTE-196 is the SK equivalent. 7amp is in there the 152 says 5 amps so it seems pretty close. Not sure what the important spec is but they seem very close to me. I have to...

L38 goes to C143 with that red wire, not the vr-7. I was off by one that is where it belongs but I guess they needed to add length to the coil?? for the xtal mod maybe? I'm reading that link you posted and I downloaded the photocopy of the procedures. good stuff! TY I rechecked those bias...

You are correct 1997 is wrong I was thinking of my 148GTL malaysia. The 142 is tawain PC-385 AG I guess early 80's ? 43002004 S/N well before the service bulletin LOL. It had dead baby roaches in it as a bonus feature. :) Thanks for the subs on the parts I might have a 4001 or two.. :D -Allen

Here are some pix L-38 is the best "mod" IMHO red wire routed back around to VR7 I think is where they have it going... I hate to touch it LOL I should ohm it out just for fun... >>>>>>>>>>>>>>>>>>>>>>>>>>>> [/IMG]

It has not been done. I went ahead and checked the voltages in and out. 13 in 8 out on the three outputs. I am going to check it for the other service bulliten and then look for that diode you mentioned. thanks, -Allen :thumbup:

Hey Thanks! I have the bulletins I have not checked to see if they have been done. I have to tell you many of the mods were done some not so much wires twisted together and electrical tape ( LOTS OF TAPE ) used to hold them together.. One had , I kid you not RTV holding them together.. must have...

Hey, I have this old (1997) 142GTL. It got it modded every possible way I think P.O. It has low power so I lifted the legs of the 1306 and 1307. The 1306 tested bad. I had a 1969 and put it in but now I have ZERO bias current. Previous owner had the voltage turned up to over 15 I backed that...

This worked for my old 142 gtl thanks. I wonder if the green stuff will harden back up or if maybe a dot of finger nail polish should be used. On a needle or pin or toothpick? It moved vet easy with the heat applied I thought I broke it. LOL -Allen <More audio>
