Don,

????????? You have some mighty fine tubes to make up a bunch of nice amplifiers. My old mentor, Eric, WA4VVI(SK) would run 4 813’s at 4KV! I have an RCA SB-1K Radiomarine amp that uses 3-400Zs and lazily will do a 1KW at 2800VDC. 4-400s you could tie the grids together and with a little extra drive, make a fine amp. So your possibilities are endless. Yes, I run AM also, (my primary mode!).

Subject: [ham-amplifiers] Dilemma

?

Over the years I've collected parts to build an amplifier. Life got in the way during most those years but now I find myself with the time and ambition to build an amplifier for my boatanchors.

?

As far as bottles are concerned I have a bunch of 813s a 3-400Z,. couple of 4-400s and of course the usual 811s, 807s, 6146s........Got plenty of iron for a power supply up to 3kv.

?

Need some direction as to which way to go.? I operate 40 thru 10. Have a soft spot for AM. (yes I'm old) but do CW and SSB.

?

Finishing up a 350 watt modulator.

?

OR should I forget all this stuff sell it and buy an amplifier.
