I recently aquired a old Tapco mixer from a co-worker. (I was buying a drumset from him and he through in the Tapco). Well tonight I came home and had some free time to waster so I decided to investigate the old Tapco. I plugged it in and it turned right on and connected some mics etc to see if signal was going through and all was good. Well seeing as i also aquired a perfectly fine Yamaha mixer from the same gentleman on the same day, I opened up the back to see if there were any goodies. all the contacts were inclean and every pot turned cleanly so i peeked closser to see what types of ICs there were, and what do you know each channel has its own seperate PCB on wich are 5 RC4558P. There are 12 channels on this mixer thats 60 4558s... along with the random others throughout (about a dozen+). not to mention all the potentionmeters (bout 120) each one having a fitting knob, lots of stereo phono jacks, alot of cable, and a few lm301s. There will be alot of toys being made soon :icon_biggrin:
go on ebay search for dead pedals and such if ur jus looking for parts to cut out or be inspired by! :) dead pedals are my dream gift... my birthdays the 16th of this month btw... :-D anybody need and address to mail them to?
i, personally, would keep the mixer as is and continue using it.
you can still buy pots, 4558s, and jacks, you know... ??? and a decent mixer will cost alot more than that...!
By the time you carefully desoldered and removed a 4558, you've 'wasted' enough time to buy you a new one, IMHO. The pots might be worth it though....
