Hi Modialfan, Love the work you did on Dr K's Aragon 18k. Would you have a schematic for the 18k? I'd like to do the same z-foil resistor upgrades and need the resistors values for R1, R3, R4, & R15 & R16. Do you recall the resistor values or perhaps have a copy of the parts order, something showing the values for these placements? Thank you in advance!
