Hi Carl and the others,

I have now closer information abouth the russian triode GS 35 b.


My special thanks goes out to DJ5RE, M0AIU Gerard and LA9DAA for the 
information!!!!

 The GS 35 b troide provides continous wave generation 
in external-feedback selfsustained oscillators and amps at up to 
1.000 MHz in circuits with a common point at grid

General information:
Cathode: indirectly heated, oxide-coated
Envelope: metal-ceramic
Cooling: forced air
Height: at most 177 mm
Diameter: at most 100.2 mm
Mass: at most 2.8 KG


Basic Data:

Heater voltage, V: 12,6 
Heater current, A: 2.65 - 3.25 
Mutual conductance (at anolde voltage 2.5 KV, grid voltage change - 1 
V, aonode current o.4 A), mA/v: 25-40
Penetration factor (at onode voltage 2.5 kV, grid voltage change - 
200V, anode current 0,4 A), %: 0.8 - 1.2
Operating pint (negative grid voltage at anode voltage 2.5 kV, anode 
current 0.4A), V: 12-6
Interelectrode capacitance, pF:
input: 18-24
output, at most: 0.12
warm up time, s, at most: 90
Output power, W: at anode voltage 2.5 kV, anode current 0.7 A, 
wavelength 60 cm, at least: 800
0.8 A, wavelength 30 cm, at least 350
Output power over 500 h of service (at onode voltage 2.5 kV, anode 
current 0.7 A, wavelength 60 cm), W, at least 600

Limit operating values:

heater voltage, V: 11.9 - 13.3
Anode voltage, kV: DC: 3
instaneous value: 6
grid voltage, V: -400 to + 120
cathode current, A: 1.4
Dissipation, W:
anode: 1.5 * 10 3
grid: 26
Temperature, C:
anode: 200
grid and cathode leads: 120

Maximum Rating:

Anode Temp, deg. C: 200
Cathode Temp deg. C: 120
Anode Dissipation, Wt 2000
Anode Voltage, V: 3000
Plate Current, A: 1.4
Grid Dissipation, Wt: 26
Grid Voltage, V: -400/+120
