Well, Ranch55 stupid me ! I found out what I had wrong I wasn't really thinking and I have seen them this way before and I saw the term "stacked" in the parts list just like they had with the 2 resistors on the output combiner and I had these stacked which doubled the value amp seems all good...
I moved and set the adjustable cap to 130pf and put it down where your 130pf mica is, I may just leave the tuner there for a input tune, I may have to wait till the 2200pf cap comes in as I don't have one on hand, I tried one that was 2725pf but the amp really isn't working properly still, if...
10-4 Ranch55, yeah I did try it the way yours is last night but not with near as large of a capacitor so not sure if that may be my issue. It would only dead key about 2 more watts then my radio and with any modulation it would swing backwards! I will try a larger disc capacitor later today and...
Ok, I tried it out tonight , it keys but had no power output and I noticed where someone had disconnected the wire on the relay that goes to the input splitters on #8 on the relay. Now I am somewhat confused by the color schematic I have that shows how it actually goes does anyone have a photo...
Hey, Ranch 55 do you happen to sell any parts for Texas Stars, I could use a board for another one I have that is a twelve guage as it had #3 board missing when I got it .
I will keep that in mind for future tests ! Thank you Nomad . Wished I had know about those bias resistors from the start but I am kinda new to pill stuff and learning, sooo guess I learned a hard lesson there ! Six pills I have are a gain of 72 and these 2 new one's I had to replace are a gain...
It sure did ! Real quickly! I just hope all the other transistors are OK the 10 ohm resistors on all the other transistors are not burnt so I hope they are OK and I learned a cheaper lesson here !
I got off work and was anxious to get home to check this out after reading your link to that thread Cable Guy and sure enough, even though they looked ok the 1.6 ohm bias circuit resistors are definitely bad
Well, I got it finished up last night and put a 2 watt key into it and the amplifier keyed and shut my power supply down in one second time, to my misfortune it blew both transistors on board #4 so now I am not sure about finding the issue but obviously there is a short somewhere while it is...
