Hi Les,
I bought mine from E-Bay a year or so ago and it has been chugging along at
5 watts for my beacon with no problems. Lowered power to 5 watts and put a
small fan on the heat sink just for grins and giggles. No heat problems. I
notice they are still on ebay from 50 to 150 bucks - may be easier to pick
up another one as there are a bunch of non-obtainium stuff in there. Don't
know if a manual is available. Looks like a project for you if you can
still see the parts!! That is why I like working on boat anchors - at least
we can still see the innards.

Subject: [HFbeacons] Realistic HTX-100 Repair
My HTX-100 seems to have given up the ghost during the testing phase of my
new beacon. I had been running the transmitter and beacon keyer into a dummy
load to test thermal drift, etc. Everything was fine for three days, then I
came into the shack to find the unit powered off.
It powered up normally, but it had lost the stored memory of my transmit
frequency. I re-tuned the VFO in SSB mode, then switched to CW. The unit
display started flashing, and the TX indicators came on...even though the
key was not connected. None of the switches seemed to affect things...and
when I powered the unit off and back on, the condition persisted.
I removed the control knob to do a "hard reset"...but the condition repeats
itself each time I switch into CW mode.
Is anyone aware of a technician who handles repairs on these old HTX-100's?
