F.S. EIMAC 3CX800AA7 Tubes: EIMAC 3CPX800A7 Tubes
I have a few used and tested tubes for sale. They are pulled from commercial VHF service and were tested OKay for filament current at rated filament voltage. They also pass 4100 volts hi-pot testing between anode and grid/cathode/filament. Finally, they were emission tested at two power levels (20 and 40 watt input) and are provided with test data at those points for grid and plate current and output power levels in grounded grid configuration. Outputs average 540 watts at 40 watt drive level.They were tested in the H.F. frequency range, but will likely function okay throughout their designed frequency range.
My price is $200 each or two for $375 plus shipping.. Payment by check, postal money order ot PayPal. My offer is limited on quantity.
These tubes are great for amplifier testing, building and trouble shooting.
If you wish, you may contact me via eMail through this ad here on QTH.COM.

1 KW linear amplifier GS-31b tube: The tube is not new from the box, but has full output .I used it in my ex linear amplifier at 2.5 KV with no more than 300 mA due to the old house wiring which was popping up the breakers of the house where I am presently live(Queens,NY). I took this home brew amplifier to another location and I loaded it into a Drake 1KW dummy load at 900 W output to check that it works. Also I have the 2 milliampermeters for grid and plate. I am asking $ 100 and split shipping. I have the picture of the amplifier I build it myself. Accepting a check or Money order.Thank you for reading my ad.; Listing #1684447 - Submitted on 04/25/24 by Callsign AB2DP, Modified on 04/26/24 - IP: syn-098-014-050-140.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

For sale 3cx1000a7 power tube: Used 3cx1000a7 (used in old alpha 70, i'm told). Am told it is good but have no way to test it. A rare tube used, priced new at $2,600...but most are sold out. $200 OBO plus shipping. I will only sell to experienced ham as i am offering a full refund if it's not up to par. Those inexperienced at tuning tube amplifiers could dammage this tube and then claim it was bad, not going there. 73's kd7ouy; Listing #1684226 - Submitted on 04/23/24 by Callsign KD7OUY - IP: 21.sub-174-204-2.myvzw.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
