Well I thought I had the issues ironed out of the VRM in my TC-15.....but, I am not noticing a drop in volume at all to my ears? I have tested the B+ voltage drop and it goes from 385 V to 381 V when turning the pot from one extreme to the other. Should there be more of a drop in the B+ voltage? How extreme is the volume change with this circuit? am I expecting too much? Has anyone had this issue or have any advise what to look at, or what the voltage drop values (range should be) thank you in advance for your help!

It's not working. B+ should go down as low as 100. Recheck the components & wiring.
