Miks, it is incorrect, my friend want GS-4B, not GS-7B, sorry.Chinese same product was called FC-4G , please view http://www.jingguang.com.cn/ArticleShow.asp?ArticleID=126, My friend is a vacuum buss
Hi! Does any man have the experience to mods AL811,AL811H or AL572 to 6m?My friend want to purchase one of them(dup to the low price) and mods it to 6m band. but I can not confiem this,because 811A a
There is a 811A 6m amplifier built by Japanese, see: http://www.n-mmra.net/radio/811/811.html But he using single 811A, should be stable. Hsu _______________________________________________ Amps mail
The amplifier input:3W, output:50W, the volt of plate:650V orso . it seems not too bad. there is another website anout 811A 6m amplifier:http://www.nitrophotos.com/811a_amp.html. it published in QST
I have an EIMAC 4CX1000A in origial paper case,NOS cndx. $170 shipped. Hsu _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/li
Hi,Guys, Why many Amplifiers using cathode driven?why not grid ? it with only one advantage of cathode drive: it seems more stable than grid drive.but it needs Pi input network and more driving power
Hi, I just finshed my first project :without HV transformer eight FU-50s(Same as Russian GU50) GG 800W amplifier, the next Plan is four FU-251F(Same as 4CX250B) G2DAF amplifier,I would like to hear a
Hi ,Peter, Thanks! Could tell me the exact reason? the non-linearity or 4CX250B's weak grid and screen?I like novelty, like my last project,although I'm a begannner in amp(btw,I'm a skilled a electro
Peter, I have seen the debate about G2DAF many years ago in the list, But I want to know, the G2DAF amplifier's IMD spec. if it did not under -30db or -25db, it should be valuable. 73! Hsu -- Origina
Thanks Peter and some people give some more information! 73! Hsu _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amp
Peter, thanks for you information again! GU 50 is Russian transmitting tube , same as the Western SRS552 , LS50 or P50/2, in China, Chinese made was called FU-50,it was used in some Chinese aircraft

Hi, Many discusstion about this question, thanks everyone! Many years ago , some AF power amplifier uesd 811A in push-pull, worked in Class B or Class AB2, I think we can use similar design in RF amp
Few years ago I hear that there was a circuit published by Eimac of an HF amp that used four 4cx250s, Could someone send one to me(picture file will be Ok) ? or simlar design will be better, I'm want

Peter, I don't think so, the output impendence should so high,if I the voltage of plate=3kv, current=0.8A, the output inpendence should be 1500ohm.I just finshed the 8xGU-50's amplifier, it used a tr
