Cool! Thank you for your comments. :) Thats a very strong output for a 68xl. Props!
If possible, please post a video (if you are able to) of your claim of the uniden pc-68xl (with the 1969 final) on the bird first on avg mode, then on peak. I would like to see if while holding a steady...
Got my hands on a Mod Squad modified Uniden grant LT and all I gotta say is "wow"! The strongest STOCK final I ever seen on the bird meter. 2 watt dead key and swings to 11 watts avg on 14.22 volts. Peak about 23 watts bird. Sideband does 20 watts avg power.
My question is that is this more...
Now its coming together....this is what peekaboo said about the messenger 2kw STOCK bias scheme:
I know I am bringing an old thread but this amplifier was built this way by messenger. i have worked on a few of them like this. The bias design needs a little work. If a pill shorts out and send...
For me, a bit more watts vs ab-1 (from what i was told by Justin). When i sent the amp to him (in 2005), just plugging in the amp to the power leads would cause it to get hot unkeyed.
Justin said it was a manufactures oversight and fixed the problem and said it had to do with the bias circuit...
Thanks for the kind words.
The backup battery (the one connected to the power supply) is a big one and that has a lot to do with the peak watts for a short duration. Bird peak meter fine, calibrated by birdman Tim NM3E. If you take notice in the vid, the first test was done with the amp on...

Selling because upgrading my DC stuff. I finally decided to put her up for sale. PAL "buddy" mobile with (1) 8950 tube. With a uniden grant xl dead key 2 watts swing 7 AVG (20 peak bird) box does about 75 avg (about 175 bird peak). Video of this claim below. Since i posted this originally a few...

Nice! You know whats funny? I have a m4v that does not have that ground scheme. Ill post pics soon
I love collecting rare stuff.....Thanks for the props :)
Damn peek, you got some sweet stuff also! I like your combiner scheme. Clean.
More stuff out of my messenger amp stash. Here i share with you the first pics published of the inside of a messenger M1500FR Turbo.
Enjoy.
PS if anyone has the history of this rare amp, please chime in at any time. Thanks
:)
Yes they are a bitch to disassemble. You gotta actually unsolder the coax going to the so239S before you can open it. Also, I retapped ALL the sheet metal screw threads on my messenger 2kw and converted to metric. That way, i wouldnt worry about wearing out the threads or the screw coming loose...
I didnt know that you dont always have to have a tuned input. Maybe it was built this way. If so, easier to tune with one knob.
I read the tutorial here on how to tune a ac amp. Im following those instructions but only with one tuner. Is there another way to tune this one knob amp?
