She survived a practice last night. VERY loud (one EVM 12L in TL806 cab). Thank God for the Master. Although the master HAS to be over 3-4 before she starts to sound great.
The overdrive sound is not as great as my TW Express. So still some tweaking to be done.
Now that the amp has settled, I decided to revisit the amp and finally address the dropping string to achieve the desired voltages as per Talbany's layout for a 2nd gen build. V1 and v2 were approx 10v down and the built in dumblelator 10v too high. B+ on power tubes was also approx 15v down. Because this is a Export Bassman PT, with multiple primary taps, I went from 240v - 230v tap (simply select the voltage selector on the back of amp). This allowed me to get the B+ up.
Being the lazy type, I have to admit, the thought of "tacking in" various resistor combinations to achieve the "holy grail" voltages did not sound like fun.
I have to say, I am glad I did this exercise. The amp sounds much better and the tone controls (including jazz/rock, mid boost) do seem to be more even. I was getting a HUGE diff in volume between Jazz and Rock settings. Voltages are now within a few volts of the 2nd gen posted by Talbany in the files section.
Only 2 problems to solve;
1. Mid control does not seem to do much.
2. The accent switch does %$@£ all!! It is a 1uf as per layout and schematic. I have tried different values. Reverse polarity etc. No luck
