Theo, I'm gonna step out on a limb and assume you meant cap upgrades, rather than "cap bypassing." Bypassing isn't the first step to take when tearing into a stock Cornet. Start by replacing these caps:
C200, C206, C208, C203, C202, C204
You need to decide how much you can spend, but an inexpensive route would be to replace them all with Sonicap Gen I. That'll set you back about $100. If you want better results and you're willing to spend twice as much, I recommend this combo:
C200, C206 --> Dynamicaps (1uF) $76 from Sonic Craft
C208* --> Mundorf Silver/Oil (1uF) $95 from SC
C203* --> K40 PIO (.1uF) $15 from: jimmcshane@prodigy.net
C202 --> Sonicap Gen II (.047uF) $10
C204 --> Sonicap Gen II (.001uF) $8
Everyone is going to give you different advice. There's no absolute right or wrong. You have to decide how much you want to spend.
Best of luck,
Mark
