Hi. I'm new here and this is my first post. I am in the process of building an amp based on 29KQ6/PL521 sweep tobes. I searched the web and found enough information to complete the project but I can't find an acual datasheet.
The tube was developed by RCA around 1974 (AFAIK). I'm wondering if anyone out there has an RCA Recieving tube manual that lists this tube. Thanks in advance.

Yes, and thanks, I looked at the link and it said RCA 1975. I could not remember where I had saeen that before. Like I said, I searched the web.
Just in case you are curious (why would you or I be here)?
the amp is going to be a direct drive amp for electrostatic loudspeakers.
The choice of the 29KQ6 is $money$. I'm getting 10 of them (8 for the amp + 2 spares) for $1.00 each and I can connect 4 of them in series and not need a transformer (29 X 4 = 116). That's for the 4 "bottom" tubes. The 4 top tubes is a little bit more complicated but I've got an idea or 2.
