The circuit board material of the straight 8 front panel is fragile. The
resin
used melts at soldering temperatures. As a consequence my front panel
was munged up before I got it. Foils lifted kind of thing. I decided when

Agree about replacing lamps - we switched to LEDs
back in the day (70s) when selling these things 2ed hand E was ind. M
and F were always LED... I preferred the leds Ed#
