    Hi - Jon here...
    I have a Golden Falcon big base amp, with no tuning instructions.

    A little history on the amp - first. It was made in the San Jose CA area -back in the day- by a man named Andy Anderson. Not sure if he's still around - but they were a great amp. Untill -I think- the FCC or "Uncle Charlie" (we use to call him) came a'knockin...

    Anyway; does any techie know the proper tune method to tune this monster? It uses ten 8908 tubes. 1 drives 3; then the 3 drive 6 more. There's 4 tuning knobs - 2 for the driver section that say "plate" and "coupling". Then 2 for the final section that say "plate" and "antenna". I've tuned all for max output.

    Has good output.
    The amp puts out around 1400-1500 PEP/SSB on my LP-100A watt/SWR meter.
    Very close to that on AM too.

    So with that; who's the expert here?
    The thing that throws me on this - is the coupling section.

    So all of you "geeks wanna-be techies" - show me your stuff!
    Anybody know how to tune this monster?

    Here's my eBay listing for it:
    GOLDEN FALCON 10 METER AMP - eBay (item 200425178727 end time Jan-12-10 16:52:18 PST)

    Thanks!

    Well, I am running a barefoot station. I live in urban sprawl; which means I would get noticed if I ran any more power than I do now. The Magnum OmegaForce is good for 8-60 watts PEP, and makes the skipland trip well as it is.

    You were making it out into the Santa Clara Valley 5/9 yesterday on this MONSTER/AMPZILLA!!!
    As well as S-9+ on my meter.
    You live on the other side of the mountain - too.
    You heard me loud 'n clear when you were in your mobile in the valley - right?

    My fALCON has six knobs

    I have a Falcon that looks like the one Robb posted but mine has
    6 Knobs. The Box looks the same but with the extra knob over the two
    knobs shown making it three in a tri-angle shape. The inside looks the same
    but mine says it was made by "LDO Electronics" Mine punches 2k plus easy
    with 3 watts dead key to 15 watts Mod. Mine set for 5 years and I plugged it up and a couple of the tubes in the circle shorted blue. I turned it off until I can replace the tubes. Anyone know of a good source for tubes for the unit?
    If so please Private message me. I know there is a tube conversion but changing all those sockets would be timely. I use mine on 10 meters BTW.
    Cheers!
    Jane

    If you look long enough you might find a couple of tubes for it but the 8908 and it's brother the 8975 tubes are pretty much made of unabtainium. they are a 12 pin tube and the only tubes that have similar electrical properties are 9 pin tubes. the 6kg6 or the russian equivalent the el509 are your choices there. I rebuilt a galaxy turbo 2K amp a little while back, and did this conversion and it worked out really well. The up side here is that the EL509 tube is still in production in Russia and you can get them new for about 17.00 each. Good luck, I hope you get her up and going.

    http://cgi.ebay.com/SVETLANA-6P45S-...ptZVintage_Electronics_R2?hash=item3caa96a5ff here is a link to a auction for 50 el509 tubes for 210.00

    A friend of mine has a golden falcon I been trying to get. It has 4 x 4cx250b's in it. Would love to get it and put on the shelf. Another friend has a golden falcon. I think it is a 500. Has has stuck in the corner of his basement. I'm sure it needs tubes. But I bet I can get cheap.

    before you dismiss those tubes i would try removing them from the sockets and re insert them a few times ,this will clean the pins a bit .then do a recheck .only other way to know is a tube tester .
    could also check the caps on the underside of those tubes to see if they still have the correct value . good luck
