1776 Multiplex Echo Machine (SPST switch don´t want to work)

[Ariosto]

Hi again,
I ended happily this wonderful delay two days ago, with modulation extra PCB included. Everything works fine, sound really great -I had some issues with the SW2 because it did not fit in my box. I must desolder the whole thing and resolder short wires in order to put somewhere else-. OK, the problem is that the temporary switch to achieve the "tape speed" effect don´t work. I measured resistance in the input of the PCB and pressed the switch and it is OK. So, no faulty switch apparently. If someone else had experienced and solved the problem, it would be nice to write me a message here to give me a helping hand.

Nice regards,
Ariosto

My build also does not work with the Tape Speed. However, if i turn the trimmer from .5v set point and increase the voltage, I do hear the tape speed work. But never while using the SW2?
