air cooling output power pentode
Overall height 18 cm.
This pentode directed beam was built in 60'S to replace the tube VT-154 US WWII faulty design (degassing of gaseous material making these tubes in a few years) to continue to operate the transmitter BC-654, SCR-506
Then, this tube was a civilian use for medical equipment (power radio wave treatment) and for scientific studies on the powers of lasers
Its use HIFI is possible with good output transformer and adapted QRO
Heating 10 volts 3.2 amps
Fitting US-base 5 pins
1500 volts will max
Dissipation plate 60 watts max
Typical use class C power amplifier:
- Anode voltage 1000 Volt
- Grid 2200 volts
- Grid 3 (supressor) 0 volts
- 1 grid control voltage terminal:
- Polarisation - 100 volts
- AF power amplifier +60 volts
- RF power amplifier 129 volts
- Power grid 2.5 watts
- Plate flow 60 mA
- Power output 25 watts
The proposed tubes are new in their original box
The tubes are numbered engraved on their anode inside the tube and this number is also printed on the outside of their box of origin to guarantee the NOS in original box
Purchase multiple minimizes the shipping cost by tube
Happy shopping
