I've been acquiring parts for a TC-15 for the past few months. Bought the chassis, faceplate, and transformers from Coco. Other components - tolex, grill cloth, etc. - were from various sources (including some I had in my parts bin). Speakers are Avatar HellaTones (G12H30 and Vintage 30). Wood and various other hardware came from the local Lowe's store.
I've had the completed chassis hooked to to a single 10" speaker for two weeks while I built the cabinets, and the amp sounded excellent - lots of "sparkle" and punch - but nowhere near what I knew it would do through a larger cab. I finished up the whole thing last night, and was able to give it a perfunctory test, but today at church was the real "road test". It was a 7-piece group (acoustic guitar, bass, drums, 2 electrics, and 2 keys), so we were able to play everything from straight-ahead rock to laid-back worship music. All I can say is WOW! This amp is just wonderful! It sings; it sustains; it whispers; it shouts; it howls; it feeds back in the most pleasing way. This really is an outstanding amp - one of the top two most musically-satisfying amps I've owned (out of dozens and dozens).

Pics and a little description:
This is the first few parts orders. Transformers, grill cloth, Tolex, piping, Garolite circuit board material, various components, and sheet metal. I had originally intended to make my own chassis, but my tiny sheet metal brake just wasn't up to the task, and the one at the local high school welding shop was a piece of junk, so I ended up ordering a chassis and faceplate from Stephen at Trinity Amps.
Just a couple of pine boxes from common lumber at Lowe's. I used a 1/2 inch finger joint jig and a Craftsman router to make the basic boxes, then added bracework from 1x2 inch stock. The edges were cut with a 1/2 inch round-over bit, and then the whole thing was filled and sanded. I really don't like sanding ....
After what seemed like weeks of applying Tolex (but was really just two days), I attached the grill cloth & piping (another job I really don't enjoy), installed the rest of the hardware, put in the speakers & chassis, and fired it up.
The finished product: My own Trinity TC-15 amp.
This amp was worth every splinter, soldering burn, cut, bruise, swollen hands, sleepless hours mentally going over the next step, and drop of blood and sweat that went into building it. It is, quite simply, an outstanding amp.
If I had it to do over again, I'd probably still do my own cabinets, but I wouldn't try to buy the parts piecemeal; I'd just order a kit from Stephen at trinityamps.com.
If someone wants to build a professional-grade amplifier, you can't do better than Trinity's kits. If you're lacking the space or tools to build one, just order an amp from Stephen. You'll be glad you did!
