Thanks for posting the pictures of the MK II. I originally wanted perforated brass for the top and while I think the black looks good, the brass would pop I'm going to do the brass but. my projects are on hold temporarily though. A fall from a ladder on Sept.19th resulted in a compound fracture of my left ankle. I am restricted to bed with my leg elevated. I have external fixaters supporting my ankle with surgery scheduled on 10/6 to pin and plate the bones, No weight on the ankle for three months and at least three months of therapy to follow. When I am able to sit at my workbench again, I am going to finish the soldering on the ST-70 with K&K driver. Board is done with the leadwire work yet to do.
Chassis work is my own of course with bubinga as choice of woods. Output tubes will be reissue Tung-Sol 6550's. Top plate is aluminum and will be powder coated white with a textured surface. Picture included to give you an idea of what it will look like upon completion. Also including a picture of a Mission table finished just before the accident for the VPI 16.5. Wood is red oak.

I finished my RAKK DAC before the summer took hold here in Tucson. The chassis is made from 7/8" Bubinga with 45 degree joints in the corners and where the top meets the sides. Biscuits are used to reinforce the joints. The inside is drilled and routed to countersink the male RCA's, power switch and chassis mount male IEC so they can flush mount on the outside of the chassis. The black dot on the rear panel is Gaboon Ebony. I use it as a calling card on my wood chassis'. The power supply is mounted on the left with three boards mounted on the right separated with nylon stand-offs. The Tent clock board is on the bottom, RAKK DAC board in the center and the passive output board is on top. Hook-up wire is fine silver. Power cord and interconnects are made with fine silver as well. Previous DAC was from Scott Nixon (Tube DAC) and the RAKK DAC is a major improvement across the board. Thanks go out to Kevin for his assistance during the planning stages for this project. Construction of the electronics went without any problems and was working flawlessly when powered up.
A couple of other projects I wanted to show you. DRD
300B
with 6CJ3 damper diodes and a 6AN4 driver. Chassis is Chechen, a Central
American hardwood. Second picture is an Ultrapath with a 5V4 rectifier and
Raytheon 6J5GT's. Chassis is Paduak and my son and I built this for his
system. To be so lucky at 23yrs old.
