[Boatanchors] Converter info

[Glen Zook]

The circuit should be very close to the Ameco CB-6.  The manual shows a 6ES8 as the r.f. stage.  However, the 6ES8 is just a slightly lower noise version of the 6BQ7.  The tube "pin out" is the same and you can substitute one for the other with the difference in performance hard to measure.

Here is the BAMA URL for the Ameco CB-6:

I'm hoping someone can help me.  I have an old old homebrew rig which is labeled as being a 6 meter transverter.  On the chassis is a PC board that says International FCV-2.  It is missing one tube, but has a 43 mhz crystal in it, so if it is in fact six meters, I suspect a 40 meter IF output.
I've searched online, and while I found an old International Crystal catalog, there is nothing in it about converters.
Any comments, help, or thoughts would be appreciated.  I did find one reference online in an email from a ham who had one and he indicated in the post that his had a 6BQ7A as an RF amp, and a 6U8 as an oscillator, but that was the extent of it.  He was also looking for a manual years ago...
