... and I'm not quite sure what to do with it. I opened it up to make sure there wasn't a yucky old battery in there - it's been in the garage for over 15 years. Apparently none the worse for wear either, I popped in a 9V battery and off it went sounding as good as ever. Problem is, I stopped using it over 2 decades ago because it has no 9V jack for a power supply. I hated using batteries for stuff even back in the 80's. Can a DC input be installed?

Sure, or there are even converters that latch on to the existing battery jack and have a standard power socket on the other end. Can't recall where I saw it though.

I’m sure you can send it to Analogman for a conversion, or get a 9v battery cable adapter

The sax player in my band had one of these, all beaten up but still worked. I cleaned it up and gave it back to him as I liked it on guitar but not bass, and he got $225 for it. For that reason and because a battery will last about 500-1000 hours in it, I wouldn't bother modding it.

My Truetone CS12 came with one of these, that plug right into the battery jack itself. If you are in Saskatchewan, Canada, it is yours!

It's worth money. It won't be if you mod it.

Well... I already filed a triangular gap in the case so that the battery cable could be on the outside, so I imagine that it is "modded" enough to already be devalued. And to be fair, it can't be worth that much - what are we talking here, $150 - $200? I think I'd rather keep it, mod it, and use it. However, I'm also open to offers... ;)
