Hi, A month or so ago, I found that my cab was unusually muddy sounding. After further investigation, I discovered that the protection bulb had blown. I thought, "oh, no sweat I'll just pop down to the electronics shop and pick a handful up." Ha, no chance. I've been searching for weeks now and no joy, so has anyone got any idea as to a. What the heck type of wacky bulb this is and b. Where I'm likely to get some? (bulbs) I'm getting a bit anxious now becuase I have a row of gigs lined up starting in a couple of weeks Here's some photos of the one I removed. The straight wires on either side aren't part of the bulb, they've been soldered on (by Ampeg) to mount the bulb onto the circuit board. Also, in case these bulbs aren't available easily, what voltage and wattage are they so I can find an equivalent? Thanks people, Josh West Yorkshire , England.
