Title: Speaking of funky tubes Post by: KM1H on October 14, 2009, 09:11:17 PM Does anyone have a 592 for sale, preferably NOS?
And for a long shot Im still looking for a good 861 or two. Also on the want list is any tube or pair capable of at least 1000W that was released prior to 1930. Actual production date is unimportant. Add a couple of 750TH or TL or H&K HK1254. Last but not least is a 1000T, 1500T or 2000T.

oops, sorry I attached the 354 twice - heres the HK-254 which is what I meant to add. Title: Re: Speaking of funky tubes Post by: w4bfs on October 15, 2009, 08:46:06 AM cruising epay just now ...saw a listing for a 861 ...good luck 73 ... John

Title: Re: Speaking of funky tubes Post by: KM1H on October 15, 2009, 11:06:37 AM Thanks Derb. Do you have anything on the other 354's such as C, D, E, F ?
I'll keep an eye on that 861 but the problem is that they dont travel well. There has to be a stash somewhere in RI what with the various Navy bases and Comm stations.

Title: Re: Speaking of funky tubes Post by: N3DRB The Derb on October 15, 2009, 07:20:53 PM here ya go. I am a plumb H & K crazie.
notice the claims made regarding the ability of the tantalum elements to reabsorb gas. Title: Re: Speaking of funky tubes Post by: KM1H on October 15, 2009, 09:12:52 PM H&K sure had some funky looking tubes and not many appear to have survived. I salvaged a pair of 354's decades ago from a trashed HB amp and finally got around to using them.
I'll follow on the 861 lead, thanks Carl KM1H Title: Re: Speaking of funky tubes Post by: W7TFO on October 16, 2009, 01:49:54 AM H&K's most funky was the '-55' series, or the 'Gridless Gammatrons'. It was essentially a way to get around the patents on regular tubes.
They were listed in a number of texts back in 1936, and found homes in some Press Wireless transmitters. Today they are super rare, and any found should be preserved. PS...I still need a socket for an 851, same as the 861 hint hint. Title: Re: Speaking of funky tubes Post by: N3DRB The Derb on October 16, 2009, 11:55:39 AM teh claims made. I shall see how many good 257B's I get out of the lot I have, but I got a Eimac version just in case. :D AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
