Yes I do see that the tone control connects directly to the 17y

Now I have looked at the schematic for a while and do really wish i could get hands on training. I just cant seem to get it.

From what I see,
1. 15AY and 15AZ are both .02,
2. 15BY and 15BZ are .02,
3. Now 12Y and 12Z are .00017 and .006 and I think 12Y goes strait to a 100,000 OHM resistor.

Am I correct so far? Icon_crazy

4. 13Z and 13Y and .001 and .03 and 13Y goes to the volume control pot?

Sorry for so many questions but I dont want to burn upall the new tubes I just bought, Icon_lol
