Have a Ashdown MAG 600 with a burned out VU meter bulb. The only direct replacement I found was on Reverb's site but has been sold for $15 which seems very expensive. I did find several VU meter bulbs on ebay that looks like it would work but am wondering if a 12v, 100ma would work. These are only going for $4 plus shipping.
-
Jeez, I'd recommend emailing Ashdown directly for information on the bulb.
-
Yes I did. Got back to me after the third try and will send me what I need.
-
They sent a new VU meter but it turns out the bulb is connected to the board. I will order one from eBay instead of waiting for another response from Ashdown. The 12v, 100ma VU meter bulb looks like a direct replacement.
-
Oh boy, that seems like a knucklehead design. Those bulbs will burn out -- just a matter of time.
If it were me, I'd find a 12V fuse style LED replacement bulb and solder it in. Might take some time to find something the right size, but there is normally a lot less heat produced from the LED replacement bulbs (from my experience in vintage Hi-Fi systems).
My approach is a kludge, but should not be too disruptive if done with care.

I have seen several LED replacments but am unclear if I would have to add a CLR to the circuit.
-
Sorry, not sure what "CLR" refers to.
There are a lot of LED replacements for fuse style bulbs out there. Most are designed as drop in replacements for the bulbs they replace. So they are not just bare LEDs.
You do need to know the voltage being applied to the bulb, but aside from that, they seem to be plug and play. I've soldered these bulbs into circuits; it can be a bit of a pain depending on the board you're working with. And if it's too much, then stick with the stock bulb.
