Hello,
I'm new to building these kits and have run into an issue I can't figure out. The Quickie worked fine when I first set it up with the stock tubes, but after switching them out for NOS Mullards, the volume was very low. I had the Quickie and power amp (HK solid state) turned all the way up and could just barely hear the music. It was also pretty distorted. The other strange thing is I put the stock tubes back in and the same behavior occurred. I cleaned the pins on the NOS tubes as they were quite dirty from 57 years of sitting around, but it didn't help. These are my current readings for resistance and voltage:
Resistance
A1 - 1.07
B1 - 1.07
A3 - 1.3 - 96.9
B3 - 1.5 - 100.5
A7 - 1.07
B7 - 1.07
4 - 1.07
9 - 1.07
Voltage
1 - 30.83
6 - 30.49
2 - 37.66
7 - 37.66
4 - 2.21
9 - 2.35
5 - 0.00
10 - 0.00
C - 3.89
D - 3.71
One other thing to note is I'm using the chokes instead of the 4k resistors. But they were working fine when I first tested it.
Anyone have an idea of what to check and what the issue might be? I've been able to troubleshoot other issues I've had, but am at a loss on this one.
Thanks in advance for the help and to Bottlehead for such a fun project.
