I have the following amps for sale: Dentron MLA-1200, uses single 8875 and has separate power supply. Like new, just worked on by our AMPS friend, Louie, W1QJ [Goodguyham]. $500 + Actual Shipping Cha
I highly recommend contacting Lou, W1QJ, who has repaired amps for me. He is a member of the AMPS list and posts here often using the nickname "goodguyham". A Satisfied Customer, Don N8DE Quoting MIK
Not sure I understand your query. TR=? I have a copious amount of relays here of all types, from miniature vacuum reed relays [great for QSK] and PC-mount SPST relays, to octal-based 24v relays of th
Lee, The one sitting on my desk is good, especially since it has a Peter Dahl Xfrmr, and the 8877 puts out legal limit [Well ... when I have 220v line installed, it will]. The 8877 is one of the most
Sounds like one of two things: Cold solder joint somewhere Bad capacitor in output circuit. Good luck finding the problem. Don N8DE _______________________________________________ Amps mailing list A
Find a used SB-230 and convert it. Should be quite easy to change output circuitry. NO, you can't have my SB-230, unless you buy the SB-104 and all the other matching boxes. Don N8DE ________________

Carl beat me to it. The swamping resistor is probably kaput, disconnected, or missing. Don N8DE _______________________________________________ Amps mailing list Amps@contesting.com http://lists.cont
Dave, Sounds like a leaky power supply capacitor. Might be a cold solder joint in the capacitor chain. Good luck Don N8DE _______________________________________________ Amps mailing list Amps@contes

Some nice looking amplifiers at this site: www.om-power.com When I travel to Slovakia in 2010, I might bring one (or more) back ... just to test, of course. Don N8DE _________________________________

Efficiency % = power output divided by (Plate volts times Plate current) The quantity in parentheses is the power into the amplifier final circuit. Good luck Don N8DE ________________________________
We all seem to forget that the 80m band has the largest % of range of all the HF bands. 160m = 1.8 - 2.0 = 11% bandwidth 80m = 3.5 - 4.0 = 14% bandwidth 40m = 7.0 - 7.3 = 4% bandwidth 30m = 10.1 - 10
Might it be the same as the rocker switches used on the Dentron amps? I have a Clipperton-L with NO transformer that might be worth having for parts. Not sure about the size of the rocker switches. D
In my estimation, it's not worth the effort, as those OLD tubes are probably quite 'gassy' from sitting around for so long. Good luck! Don N8DE _______________________________________________ Amps ma
