excuse but I'd like to mod my gbc with the pitch mod. actually I'm only have a question about that, what LTC1799 should I buy (dip6 adapter or pcb module)? or what recommended for buying for this mod?

Also I'll buy some potenciometers class A for this mod, what's value (100k, 250k, 500k...) it's better to have a good sound?
