Damn that looks like a fun item. Is it based any particular design?

 

[mig27]

Sweet!
Would you mind sharing some insight on the design?

oh yeah.... id completely missed the date thing- better sort that out......

design wise its an altec.... replaced the vacuum diodes with in4148's, built a power supply using a solid state rectifier, and changed the sidechain to a variable attack/release based on a 220k pot, a 2 meg pot, and 2 caps. simple, robust, and it seems to work fine ... put a couple of attenuators on the input and output, and it uses standard Sowter trafo's.... ill probly stick a schematic up on the synthpunk site when i get round to drawing it....

the metal work is a hammond aluminium chassis and a 4U panel rivetted to it.... ive got a selection of Q-max punches for the various hole sizes, they're great for getting a perfect round hole.... doing the metal work is one of my favourite bits of any project, but only if its aluminium- steel is a right pain in the proverbial....

which altec? 436 ...438...??

the inside looks very sweet nice work

also the back view is nice too... OK I have to say .... if you could make some labels and loose the majik marker stuff it would be cooler... IMHO

I like you knob arrangement (you still have 2 to add correct?)

would have been nice to get some cooler meters too....maybe if you light them blue .. :grin:

I bet it will sound "wonderful"

great work ... I hope you found my constructive comments helpful

I'd like to try one of these myself ... it does look great!

later
