New Valvestorm 18W TMB doesn’t seem as loud as it should be
Hi everyone
I just finished up this build and for some reason it is not as loud as it should be.
Any suggestions as to what could be causing this?
I will post voltages a little later.
Thanks in advance for any help, much appreciated
Here are the voltages
V1, pin1) 191 3) 1.5. 6) 220 1.9
V2 pin 1) 181 3) 1.4 6) 294 181
V3 pin 1) 302 3) 6.6 6) 301 6.7
V4 pin 3) 14 7) 369 9) 354
V5 pin 3) 14. 7) 366. 9) 354

Check the values of the PI cathode/tail resistors. There is something really off. The cathode should measure 10x what you have.
Also add the grid voltages of the PI to the annotations.

Thank you very much
