Hi Gingertube,
In post 6 you mention using 1609's to build a Babey Huey. Did you ever get around to it. I ask because I'm thinking of using my 1609's to build either an ECL86 or EL84 version but which one. My 0-250v trannie is going to give out a high(ish) B+. The only valve stuff I've built so far (that's worked) has been the K502 and am now removing the mods for this project.

Many thanks for your great Babey Huey thread

Bill,
250V secondary on the power tranny will get you around +300V to +320V rail.
You loose about 12V for the output tube bias which subtracts from that rail voltage (for the CCS biased versions). Either of the EL84 or ECL86 versions will be OK with 1609 Output Trannies at these voltage levels. Its at the top of what I would recommend for ECL86.
So really its your choice as to which you go for.
Cheers,
Ian
