i only have 2 working valves Roger i did send you an email
Ah OK . . .
Hope your new valves arrive soon.
There is D-16 also. Had the same issue with a friends AL811H. High input SWR. This amp is so hard to work on. W8JI, love ya bro, but arrgh. New tubes did change anything~
I gave it back to my friend, ready to send back to the factory~
Ok Roger i have three NOS OTK Russian tubes in it now it shows a plate current of 1.3k not the suggested 1.7k in the manual thats on standby
A Plate Voltage of 1.3kV you mean . . .
What happens to the PA current and the Grid Current readings when you switch the Amp to Transmit?
