Hey Everybody,

I wanted to post a HUGE THANK YOU to Bill for helping me out with my chassis design!

He took my visio dxf drawing and made it into a proper CAD file, and helped improve it on the way. Check it out:

If anybody needs help in this area, I highly recommend hiring him.

Thanks,
Josh

All the items for the pcb are on order plus the reverb driver & a few pots. I'll be using Josh's pcb and man is it hefty- He did an excellent job. I may revise my plan of tearing up the Mojotone to get parts and just buy all new. The mojotone works really well in spite of all the negative things that many have said. For me it was a great learning experience. I had built an Allen amp but the instructions were so good that all I did was follow them turn it on and play for five years, not a bad thing but I didn't learn anything other than I can follow directions...

I also got a Joshuwah, my first wah but I've wanted a wah for a long time. It is fantastic - my problems is that there are so many to choose from - I think Cr* B*by make 10 different versions If you feel compelled to support the work Josh does on this site check out the JMP Guitar site and view his offerings. I hope plugging for the admins is not considered bad form. I know he wouldn't do it for himself

After a long hiatus I am back to amp building...my primary distraction for the last year has been retrofiiting a Tree J325 milling machine https://photos.app.goo.gl/LLHf8M84eQYwP3ph6 I had put all other activities on hold until it was complete...complete is just a concept, but it is working and making parts for amplifiers (indirect 18 watt content) I routed a board the other day for another amp project.
OK I need to include direct 18 Watt content. I purchased a board from Josh about a year ago. He rewarded my assistance with his chassis design, by comping a chassis for this project. I haven't been on board much but Josh is working on a few other projects and I have provided chassis designs for that effort along with a head cab concept.
I am committed to focusing on amp builds for the next week or so and I am excited to try bringing up the 18 watt single input TMB reverb soon. Today I lay the board in the chassis as I was checking the spacer heights to ensure clearance above the reverb connectors. I thought a progress photo was in order.

. I will wire up pots tomorrow and be close to ready to mount the board.

I have 26 ga shielded wire - it seems a little small. What is recommended?

I use 22 or 20 AWG depending on what I have available.
