I have a Metz 60 CT-4 flash that I picked up from KEH a few years back. The battery is taking a charge, and the last time I used it, it worked well. I had it sitting for about a year or so, and the battery still seems fine, but the flash no longer fires. I don't hear the tell-tale whining sound anymore, and the test button won't fire the flash. I'm thinking, hoping, that this is as simple as replacing a bulb to fix. But now I'm trying to figure out if and where I can actually purchase a new bulb for this flash. Or if my problem sounds familiar, like something other than a bulb. Thanks for your insight. In fact, I'm over due and am heading over to finally buy my APUG subscription now.
