Great work and as has been said, nice to see a tube amp doing the heavy lifting
!
I wonder if I could press my TL922 into service on MF? It's lying idle since
I got my SPE 1K. Any comments on how I might need to mod it much appreciated
At the moment, I feed the signal from my Elad SDR Tx from the 0dBm output
into a broadband 1w ebay special and then the 1w goes into a Hafler 9505 and
gives me about 500W up the wire
Cheers

Hello Luis,
Please pass congratulations to Oscar and good luck on his next
endeavour. Nice to see a valve (tube) amp in use, I am still hankering after
building one myself for LF. Good to see Argentina on the MF map, I always
thought they were all beef farmers or wealthy polo players ;)
