- I'm still muddling about trying to find a workable solution for getting an 8171 on 6M. The tube's internal capacitance is a big problem. I've posted this whine previously, and have not gotten any rea

- If it's a problem, I'd echo the suggestions G8TIC made in a reply to your previous posting - consider something other than a pi-tank. You might find some useful stuff in this description of a working

- Barrie... Here's some design ideas, based on a smith chart analysis using the gsmc-1.1 program, assuming 25 pF output capacitance and 3K plate load impedance (with strays). I can run the numbers for

- Barrie, I'm the builder of the 6 metre 8171 amp referenced in Steve G8GSQ's posting. Although the output capacitance of 23pF may be considered high for a tube operating at VHF, when I built my 8171 a
