I'm Keith.
So what makes a hot rod and how is a turbo different. I have a hypnotize dcb1 black pcb built by a guy on DIYAudio. I bought it off Tom. It has Riken Ohms in the 220k and 1 meg positions and the four 220r are Shinkoh. The .22uf caps are now Jupiter copper foil in paper and wax. I first checked with Salas who confirmed these are the most important areas to improve. The rest are Dale, prp and Elna.
It has a TKD 601 pot that I am going to change to a Khozmo of similar.
I will take some internal shots when I figure out how to post pics to this site.

Hi Keith,
The "Hot-Rodding" is in direct relation to how much juice you can get through the board.
Level 1 is 60mA (standard build)
Level 2 is 200mA (Mur860 upgrade)
Level 3 is 600mA (Mur860, 2.7ohm resistor change, 14w heat dissipation necessary)
Level 4 is 2A (Mur860, resistor change. Heat dissipation by fans and heat sinks)
The difference in clarity between 60mA and 200mA was significant. I'm glad I got it done for the new owner of my old one.
New build will explore a 1.2A version. Heat dissipation will be done via the Aluminium chassis and possibly a couple of 1" fans or similar. If that's not possible it will be 600mA
Hi All,
Just a bit of an update to the build with a few pics.
Checking if the layout works !!!

Moved the fets off the board ( Firebottle ) suggestion to disperse heat through the
thick aluminum base and fit Khozmo Attenuator and Elma 6 way switch

Will run at 600mA to settle in then will try at 1.2A using the huge heat-sinks for comparison

Inputs wired using Olivers (Bigman80) Spotfire cable
I hope to have this finished soon but will wait until my wrist feels better before wiring the power.

Nice I've just been notified of a package winging its way to me from Mr Teabag
Planning to start it over xmas when I have some time off.
