If you replace the transformer with a 17V version, you will have to upgrade some other components.
Change the 1N4002s to 1N5404, Change the 2200 uF caps to 3300/35V, Change the 2 100Ω feeding the zeners
to 220Ω/2W.

Here is a way to connect the reverb module. You have two choices for the input.

Are you sure the 47K resistor at the input is correct? 470K or 1M would be better, and change the input capacitor from .22 to .022.

Hello everyone
Thanks dmeek for the suggestion, as for the input resistance of 47K, it is what is mounted, however I will try to change the value to about 1M, as well as the capacitor, I will test with 0.022, but it all depends on the arrival of the reverb tank, which is delayed due to the current situation.
Best regards.
