Very nice, I like it!
I recently threw one together myself using '74 CTS alnicos salvaged from a Kustom Tuck & Roll cab. I still have to cover mine too.
Front
Back
Temporary screws holding the back part on, I need to pick up proper hardware.
I did the partial open back deal as well because I think the alnicos sound a little fuller with an open cab. I also put in a center baffle so I can use it in stereo with a rack rig. It sits in a tight fitting dato.
My latest creation is a 5E3 I'm in the process of building using parts taken from a trashed '63 Hammond M-111.
The amp is going to require a complete gut and rebuild from scratch. 50+ years of dust & dirt soaked up moisture and caused plenty of rust up top.
A peek inside confirms it's mostly cosmetic. The tube sockets are pretty much toast though.
I've decided to also try to use the organ's wood to make the cab and preserve the original organ's look. So far I've cut it down, rejoined the sides and cut down the speaker baffle to fit. I will be putting the steel piece with Hammond badge that sits between the upper and lower manuals on the organ up top where the hole is. A piece of trim from the organ will sit above that just under the top. Another thought is to make it a split chassis and put the controls up there. I have plenty of braided sleeving and sheet metal from the organ to enclose the controls and harness for shielding. I'm also considering making the top a flip open type using the hardware from the organ bench so I can store pedals and other stuff in it. I'm taking my time and trying to make it unique and interesting. It should make a very cool little livingroom amp.
