NOTES:

1. (30 Jan '03): The "krasnodar.online.ru" server has gone through upgrade and URLs have changed in the last few months. Corrections have been accomplished. If you find links which do not work, for any reason, please advise!!
2. (17 Feb '03): Janusz VE3ABX discovered 2 dozen additional links which were added this date.
3. (27 Nov '04): Discovered that "hamradionline" had changed to "www.cqham" - dunno how ;long these links have been "dead", but they work now.


These sites are mostly Russian-Language - hope they are helpful!

This is the ham radio home page of the city of Krasnodar:

and http://rw1qu.narod.ru/rl_4_2001/rl_str25.htm

http://www.roston.ru/rv3fm.htm Broadband PA with 2 x GU-70B, 300W, 2-30MHz. Used in naval transmitter "MOLNYA-3", type PKM-20. Adjustable gain.

http://ur5fcm.h1.ru/schemes/gu74.html PA with GK-71 for FT-840. PEP 500W. All HF bands, grounded grid. GK-71 is a ("good, old") tube somewaht similar to GU-13 (813). It has however rather poor performance above, say 20MHz (my personal experience). The author (UA1FA) addresses that and uses this to his advantage (no chance of parasitic oscillations!). This may be just another site with already known design.

http://ur5fcm.h1.ru/schemes/gu74.html Grounded grid 1kW PA with GU-74 (very slow loading).

http://rf.atnn.ru/s4/uvh-b97.html QRO for 144MHz EME applications with GU-35B

http://www.hamnv.boom.ru/3gu50.htm PA with 3 x GU-50

http://www.hamnv.boom.ru/2gu50.htm PA with 2 x GU-50 GU-50 used to be a workhorse for lower power levels (50 to 300W dep. on number of tubes). No american equiv. West European equivalent is LS-50. Recently widely used for audio applications. See the tube picture at: http://home.onego.ru/~vitalybr/new_tubes_two.htm ("interesting tubes") or at: http://home.onego.ru/~vitalybr/tubes_r_1.htm

http://www.logicnet.ru/~electron/radio/schems/booster.htm Just another site with otherwise well known grounded grid PA with four tubes (6P45S, GU-50 or G-811). See: http://www.cqham.ru/pa811.htm

http://anklab.pirit.sibtel.ru/Press/RL/1994/03/rl19940353.html Good article on tube PA (if one understands it, of course). Included are PI-network calculations.
