I deliberately made the EQ and tube gain make up PCBs slim enough to fit in a 1U case. I believe several people are building stereo EQs in 1U rack mounting cases.
Mmm.. Excellent :)

Note, however, that the PSU PCB was designed for a different project and will not fit into a 1U case.

If I'd go for a cheap option, leaving the transformers and tube, would it be easy to later upgrade the unit with those parts?

It would be easy to upgrade to input and output transformers. However, the mains transformer would have to be changed if you went from semiconductor gain make up to tube gain make up.

Thanks Ian!
Think I'll wait a little and see how it goes with that mid-eq. Would be ideal to have it in.
 
Has anyone compared the sound of the Poor Mans Pultec with the original/Rich Mans Pultec ?

Good question but I don't know the answer. It is not a completely fair test because the poor man's does not have the inductive hi boost - it uses a simpler RC network to save money. The 3 band Pultec board I designed would be closer as this does have an inductor based hi boost. I know Pierre likes the 3 band Pultec but I don't know if has been able to compare it with the original.

I never had the chance to touch an original pultec so i can't compare.
The eztubemixer card i used for the amplifiers is solid by itself...
so i don't know if it sounds the same, but it's certainly a high end eq!
