The power tube ( called Resnatron ) for Tuba was developed at the RRL by David H . Shone and Lauritsen C . Marshall.
29.
Glidcop has been successfully applied to resistance welding electrodes to reduce stick to commutators, high speed motor and generator components, and microwave power tube components.
30.
The amplifier has a 5Y3-GT rectifier, 2 6V6-GT power tubes operating in push / pull mode, and a 12AY7 and a 12AX7 in the preamp.
