12000 out of mostly leftover parts

Bought this Metroamp chassis as a factory second along with the turret board from George back in 2008 or 2009. Plan was to build a chassis to burn-in tubes. Well, that project never got off the ground and this chassis was gathering dust.
Friend of mine been jonesing for a Plexi-clone for a long while so I caved and told him I'd hook him up. Added the LAR/MAR PPIMV and some other goodies like NOS Allen Bradley carbon comps and Philips mustard caps. Also added the MM 10h choke which I really like.
Aside from MM trannies, built the amp entirely from parts I had around the shop. Cut it close on a couple values. Decided to add the IEC receptacle and the marshall-style fuse holders. Chassis was not originally setup for these so modding with a Dremel was in order.
Turned out grand, only needed a slight rebias after burn-in and tweaking the input grid wires in V2 to chop the noise a bit.
Definitely a groovy sounding amp and I'm sure she will sound better as she gets played.

Yeah had the 10H. Bought the OT and PT tho. Glad I'm on the lowest price structure at MM
This was a lot of fun (again) and every one I've built is each a bit different.
Have lots of ideas for building/creating other amps just not the time anymore. I started this one in February heh heh

Yup - know the problem. Other one is having a few bits left over after each build and then feel compelled to use them in another one for which you buy more bits, with a few left over and on it goes. Sadly I have build kits accumulated ready to go when time permits
