Power valves

Please note: orders of two or more power valves are matched as standard.

For further information see valve testing & matching.

 

We thoroughly test all our power (output) valves on a digital measuring device pre dispatch.

Power (output) valves included in our valve kits are all specially selected & matched where required.
All power (output) valves are checked for the following:

 

Plate current (mA)
Transconductance (Gm, mA/Volt)
Emissions
Grid leakage
Short circuits
