Does anyone have DC operating conditions for the Russian GU-81M pentode in class AB1 or AB2, please? The only data I can find are... http://www.kvindesland.no/yl2qm/tubes/gu81m.htm Vg2 = 600V, Vg1 = ?? (probably smaller than -100V) http://www.cqham.ru/HiFi_Contester_EX8A.htm Vg2 = 800V and Vg1 = -220V. Both values seem very large. If Vg2 was lower, then Vg1 could be smaller too. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
