@Spacehead: May I ask where you got the plastic case from? It looks very much like the Voyager's case.

It is Hammond 1593X-MU , Got it from electronics store.

Not so much a build as it is a mod.
A local member here had me repair (stuff 'sploded) and mod his Melos Gold.
The mods:
 
-> Replace the photenti-crap-ometer with a DACT ct2 stepped attenuator and a ct3 source selector.
-> Replace the crappy loose rca jacks with good quality Connex "WBT Style" teflon isolated jacks.
-> Isolated the board and added a proper ground-loop breaker.
-> Replaced the input caps with Mundorf Silver-in-oil and wired them directly to where they need to be on the board (vs a random walk like the left channel does).
-> Replaced the inter-stage and to-ground caps with Jantzen Superior-Z's.
-> Replaced the final cap after the regulator section on the HV supply with a 100uf Solen.
-> Replaced the HV and LV bridge rectifiers with FREDs.
-> Did the left channel mod (reroutes the left channel interstage path over the top of the board instead of paralleling the HV power line).
-> Rewired the whole thing with Cryoparts TWCu and Neotech Teflon solid cored copper (for people who care about these things hehe).

Cheeky SOB!

John just found the t2 amp board stuffed full of prp muhahahaha   =D

You just gotta love that "prp muhahahaha   =D"

Something similar here, changed all the caps and installed both bias supplies in a Stax SRM-Xs.  This was originally a electret only amp so no bias supply but the spots were on the PCB so it was easy to fix. 
 

 
Just imagine how small this could be made today (this was produced in 1990).  Fully DC coupled, fully discrete and capable of being run fully balanced.  This one has mosfet outputs as well...

Why take out the balanced preamp outputs? that was a very cool feature of the SHA-gold.

We'll put them back in when we change out the out put caps for that section to match the rest 
He has no immediate need for them atm.

Congrats!

Not sure if this qualifies, but, it was fun to build from spare parts (except for the box and resistor).
 
AMB MOSFET Tester/Matcher in-a-box:
 

 
Does this qualify as point-to-point?

Works great! Now to build something real with the MOSFETS!
