Blown illumination lamp behind the retro analogue VU meter and no other
neon
or LED to show the amp is on. It is marked R51 on the overlay and the
schematic from Ashdown but no V or Watts. I will probably up the dropper
and
put a blue LED in there. Anyone happen to know what sort of rating and
voltage it was ? Connected to full + to - 15 V dc , so 30V through a
1/3W,
220 ohm dropper to this 1/2 inch long, 1/8 inch diameter wire ended
bulb.
Ohm's law fashion presumably about 30mA, 28 Volt. No chance it was a
neon
or
phospher lamp ? as it is a frosted glass bulb, so cannot see the inside.

While at it anyone know of a better way of mounting the VU meter so it
does
not push in if touched from the front.

Have not had to replace the lamp on one of these, so cannot offer any more
than you have already worked out, except to say that they are a very
innefficient company to get parts out of, and that one of the music store
owners that I do work for, calls them " Trashdown " ...

I currently have two of theirs in, one which requires an output tranny,
and
the other, a mains tranny. They have both sat here for 6 months now,
waiting

Seeing the price of one BUZ900 or 906 of 13 to 18 GBP reminded me to start a
thread for any generic (cheap) power FETs

Because of the mm or so protrusion of the plastic bezel through the
aluminium even seriously side on view is quite nifty.
