Could datasheet you confirm this data, please? The suppressor grid g3 is tied to the cathode unless a value of Ug3 is specified. I' ve qb3 seen lots of configurations for these tubes in PA operation. Click on this or any other picture to see the large size version! Qb3 300 datasheet.
500V Vg2= 0 ( tightly grounded) Vg1= qb3 between volts to get apropriate Ia. I do not recommend you to use qb3 the this tube I went through two sets in fairly rapid succession before I threw the towel in the ring. Also PA3BIY Preamp rebuilds for sale.

Recently i got some spare QB3- 300 tubes ( equivalent SRS455, 6155, 4- 125) so I´ m planning a new SSB qb3 amplifier using them. According to FLB mod by Peter ( OZ1PIF), QB3- 300 should datasheet work in G- G service as follows: Va= 2.

I am not enthusiastic about the 4- 125A, 4- 250A and 4- 400A, with the gain on 10– 20 metres falling below the European tetrodes. In general I do not recommend using American tetrodes.

qb3 300 datasheet
Designed for people who are exposed to intermittent noise, the QB3HYG banded ear plugs offer good protection with its semi- aural fit. Smooth, ergonomic pods fit outside the opening of the ear canal for noise protection, while the patented band design prevents ear pods from touching dirty or contaminated surfaces when set down.
