Re: PEN4A valve?
Could it be a PEN44? (Octal but larger spigot than IO)
Try 4V on the heater and see what current results..... http://www.r-type.org/exhib/aag0011.htm

Re: PEN4A valve?
Taken a long look at this valve and decided its a PenA4, dyslexia rules at times.
Its in good order too. Understand it was an improved Pen4VB which was a poor valve. Eclipsed by the AC/Pen, a better valve. |

Re: PEN4A valve?
The Pen44 has a Mazda Octal base, different pin spacing compared with an International Octal as well as the spigot diameter.

Re: PEN4A valve?
PenA4 is B7 base. No confusion there then!
