Re: EL2 though EL85. Small power pentode.
I have two PL95s here, one was made in the UK and the other was made in Western Germany. Otherwise they are identical.
The valves have no cut outs in the anodes so it is impossible to examine the grid structures. However, there appears to be evidence of beam forming plates. Instead of the usual suppressor grid support wires small metal tabs can be seen emerging from the mica assembly plates. DFWB. |

Re: EL2 though EL85. Small power pentode.
Closer examination of the EL85, the final valve in the series reveals that is a true pentode with a suppressor grid. Also, the construction is much more robust compared with the EL42 and EL95. My EL85s are coded CV3526. Made in the Blackburn works.
