Help with the OT in my 18watt build

[steve-o]

Hey all!
Well, I've wired up the heaters off the PT, switches, lamp, fuses, and first two stages on my preamp grid. I was hoping to get some help with 2 things:
1. I have a heyboer 18watt OT. I was sent the pdf schematic for it, but I honestly don't know which color wires go to what in my schematic. So any help y'all could give as to how to hook this up would be much appreciated. I have one output jack that will be driving either a Cannabis Rex or a G12H30 Anniversary (Both 8ohm speakers, I believe.
2. I've made some changes to this schematic (reversed values of resistors coming off the input; moved standby switch to coming off of pin 3 from the EZ81 recto, etc), but would still absolutely love any feedback anyone has on this circuit. This is my maiden voyage into amp building, so just tell me what you see. I'm going for a mellower, clean (fendery) preamp section. The power section leans more to the british side when pushed.
Thanks all!
p.s. Scott, I took your advice and got some pots with different values to try out for the cut and resistance values in the PI section. Thanks, again...

hi Steve-o!

about your schematic:

1- I think you must have a reference (resistor) to ground at the grid of the third stage.
2- I'm wondering about the huge gain of your preamp. Express/Liverpool (not knowed as clean amps) have a 68k/150K grid to ground resistor on their third stage(which's quite low) and a 10k cathode resistor which mean high negative feedback and cold biasing).
3- question to the board. There's a way to play with bias independantly of negative feedback. what do you think/have you tried this? (schem below).
yes! when wiper is not to ground there's DC on it!
you may change the value of cathode resistor & trim in order to keep the asymetrical sound of the 10k bias with a higher neg feedback...& the stuff in between....another pot to play with!

Be careful Steve-o you may get addicted to amp-building!
