Hello again:
Well I finally got things built.
As I indicated above I used the jcm800 front end. I decided on 6ak6 as the output tubes. I followed the advice from Tubelab and put 200v B+ and 10v on the cathode. I do not have a picture of the schematic, it is a pretty straight forward design. The tricky bit comes in the Point to Point layout. Transferring a schematic to the real world is not simple. It took a few redo's and part moves to get it sorted but I got it. I think it is okay for a first attempt at layout. I know I could have made a lace board or a turret board but I was focused on PtoP.
The chassis work was real easy as I have a small metal break and a drill press.
The wood cabinet work was a really fun part as I have made a few wood projects in the past and have a small wood shop in the garage. I wanted to give it the front panel a Celtic theme. The surface lace work was done with stencils and a my sand blaster. The chrome knot came from a jewelry neck pendent and covers the air vent on the front. Chrome corners handle and feet came from various DIY suppliers in Asia.
All in a fun enjoyable project. Output is measured at 2W RMS. When played through a 2x12 separate speaker cabinet it blasts way louder than I expected.
My friend, brought his guitar over to check it out so I could do the final voicing and adjustments and he could pick it up to take home last week. We had a great session with a few beers and a lot of smiles. Here are a few pictures:
