QTH.COM Ham Radio Classified Ads: TUBES - Swap amateur radio HF VHF equipment buy sell trade on line

For Sale: Econco 3CX300A7 (tests weak): I have an Econco 3CX3000A7 that I got in an estate sale. I sent it to Richardson Electronics in Florida to be tested and I’ve attached the test report.
I think I can only put up one picture so I thought the test report was most important. I have a photo of the actual tube with my QSL card and will send it to you if you contact me.
Per Richardson’s analysis, this is a good candidate for a rebuild. I am going to Hamvention this coming weekend and can deliver it to you there at no charge. Asking $150 or best offer.

pair of 6146B pulls, test good, balanced: Found in a box from a recent hamfest, pair of used 6146B output tubes, same construction, test good on my Triplett 3444. They test a little bit above halfway between new and used. No burn marks or signs of abuse. Come in white boxes as shown. These would be good as a set of spares, or for testing a rig you are working on where you don’t want to risk frying a new set of tubes. $10 for the pair, plus shipping. PayPal, money order, cash, or check if I know you. 73 Bill W9VV; Listing #1728042 - Submitted on 05/03/25 by Callsign W9VC - IP: c-68-38-21-15.hsd1.in.comcast.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
