Crate BV150H amp , safety issue
 

Second one I've come across where the standby lamp thinks it is a lighthouse
( for a short while). When cooled down the neon's now black internal dropper
, 1/3W or so, measured 550R . The switch housing says "110V lamp", surely
I'm not the only one to have come across this arson issue. I don't have the
schematic for the 150 , the BV120 schematic has the neon on the HT ac side,
not the rectified and smoothed side. I've not taken the amp apart to explore
wiring but have not found a dropper additional to the internal neon set for
USA 110V mains wiring purposes. What is the work around , separate neon ala
Marshall valve amps etc.

While at it, I suspect (not examined yet but suspiciously bright) that the
mains-on neon is also set for 110V like the other BV150H . I'm in 240V land
and that will need accommodating as well. This one 2003 manufacture and
without attention, that dropper will go pyrotechnic in ten more years of
use also

What does the coffee maker?? "sticker" say, for 120 V or 240V
operation?

The paper label at the mains fuse says
"U EXPORT 240 VOLT"

Strangely both sw marked Arcolectric , England and 110 lamp, generally only
building site kit would use this in England. Mains one dicoloured enough so
impossible to read colour bands measured 47K so both set for 110V presumably
.. Replacement ones have plenty of space to change the dropper, 1 150K as
original for 240V land , and the HT standby 150K dropper replaced with
560K//560K
