 VU meter Question, I know it's not an amp question
--------------------------------------------------------------------------------
 Hey I just bought a board on the cheap because the VU meter lights have burnt out. Would anyone know of a place on the internet where I could learn how to replace them? The board is an older yamaha 1204. I could snip the leads and connect new lights but I'm not sure that's the proper way to do it.

Thanks in advance.

 The bulbs could probably be matched up with something that is available if I knew bulb size and shape, basing (or wire leads) and operating voltage.

 I had the same problem with my Kelsey mixer board.
When I looked inside to see if I could just put in replacement bulbs. I found that it had some kind of small bulb with no markings, built into a socket that was stuck to the back of the meters with silicone.
Once I checked the leads and found they ran at 15V, I looked around to see what I had handy.
I found a couple of Honda side marker lights, complete with sockets, wire and easily replacable bulbs.
12V cars actually have 13.8-15.2 volts when the alternator is charging so they are happy with 15 volts.
Scrape off the old ones, stick the new sockets to the translucent back of the VU meters, solder in and enjoy.
