[Boatanchors] Converter info

[RAY FRIESS]

Looks like I am about 90% toward getting the 6 meter converter going that I pulled off of an old homebrewed rig.  Thanks to the great advice and help I got from you folks here, I have the spec sheet and the schematic for this International FCV-2, model 50.  Now, I just need to locate a 6BQ7A tube for it.  The 6U8 is still on board.  Our good friend here Glen Zook says a 6ES8 will also sub for it.

SO .. if anyone has a spare of either that they are willing to part with, let me know.  I'll be glad to pay a fair price, or if you have several extra and just want to give one away, I'll pay for postage.

I have an Ameco power supply that was used for their 6 and 2 meter converters that will work to power the converter, and if it comes down to needing to, I have the transformer from the homebrew the converter came on, and I can whip up a small power supply.   That's why I say 90% there to firing this converter up and deciding which receiver I'm going to pair it up with.

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...
