Quick progress report. Transformers are on the way to me so I can check the new mic pre layout which accommodates Sowter, Cinemag or Jensen input iron. If that works out I'll update the PCB layout and order what will hopefully be the final version prototypes.
The Pultec 3 band and Helios 69 EQ PCB prototypes arrived today. To recap, the Pultec 3 band will do, one one PCB, all the poor man's EQP1A, with or without the mid boost/cut mod and also allows you to build an inductor based hi boost just like in the original Pultec EQP1A. The Helios is a new design that closely follows the original Helio 69 type EQ. This means it can be used in both tube and semiconductor designs.
I also took the opportunity to order some more of the original EQP1A PCBs, plus some poor man's tube gain make up PCBs, plus some of my phantom PSU PCBs and some tube HT PCBs. I plan to offer all of these via the 'White'market in the near future.
Cheers
Ian
