Looks great! My Triamp is full of those metal film resistors and those exact same blue electrolytic capacitors you have pictured on your board. I'm hoping that means they're the good stuff, since you're using them too?

Nice!

Thanks man! I don't have a lot of metal film resistors in this amp. There are some, but it is mostly Riken carbons... The blue electrolytics are BC caps - very good stuff!

Ok, more progress today. I finished (what I could without the board in for good anyway) the on/off/standby stuff. Then, I installed my board and cut the wires that come from the board to the correct size so it can be wired in. I labeled all the wires that are attached under the board so I would know where they go. I need to wire the preamp filter cap under the board and I need to wire in a new ground wire for the loop because I cut it too short thinking it was another wire - no big deal. The choke, last OT wire and one more power TX wire need to be cut and soldered as well. That stuff needs to happen when the board is in for good...

I also soldered in the ground bus wire on the pots just like my layout drawing. Bent the lugs up and twisted them to get some 18 gauge bus wire through. The colorful bundle of wires with the twist ties go to the foot switch and the long red wire from the last relay DIN goes to the relay power supply board. Before I can wire in the board and start testing this, I need to create and build a new small relay power board (the one I built originally won't work with one of the components I'm using) and drill the chassis for the board and 6V AC power transformer and wire that stuff in. Once that is done, it is a matter of wiring the board and the loop components in and it'll be test time. Maybe a few more weeks until I fire it up for the first time. Oh yeah... I, of course, still need to build the foot switch which is no small task... Here are the pictures:

Thanks man - a lot still to do, but it is coming together!

That look s awesome. Fun project i bet. I have no patience so I would go crazy, but hats off Steve. I am anxious to hear it. How many hours go into a project like this? When do you anticipate having it done? :rock:

Thanks man! I can't even compute the number of hours since I designed this basically from scratch and the chassis and board had to be cut custom by me. The layout design took me the longest - I had to learn CAD so I could do it to scale. It is quite an undertaking. Not sure when it will be done, but I should be testing it in a couple weeks and then I'll know where I am...

all i wanna know is-how much to make one for me? :yes:

i need to reread the thread, i cant remember what all you were trying to do on this one. a modified jose, right?

Cool! Haven't settled on price yet, but I'll let ya know when I'm closer... If you go back to the first page, the first post has a complete description of the 3 modes of the amp...
