Substitutions for RC4558P (King's Hand Overdrive), 2N5457 (Clandestine Preamp),

RC4558 is pretty common so I feel this is a weird place to substitute but it can be substituted with a lot of ICs.

I'd probably go with LM833. Otherwise any IC (RC/MC/CA/LM) with the numbers 4558, 4559, 1458, NE5532, TL072, TL082, OPA2134 (expensive).

For the 2N5457 I'd probably go with the SMD version MMBF5457 soldered to an SMD adapter board.
 
laundryman - 2N5457 replacement is a very common question, not only here.. :)
There's no 1:1 replacement. You can try J202 (MMBFJ202) MPF102, J113 (MMBFJ113), BF245A, MPF4393, 2N5458 (MMBF5458).
And of course MMBF5457 (Tayda: out of stock)
 
Thanks a lot for the help everyone. The 4558 substitution seems pretty straight forward so I grabbed a couple of options from Tayda, as well as a couple for the 5457.

I really appreciate it but I'll try out a couple of the substitutions I got from Tayda. Thank you though!

Now the new problem....I'm just now realizing that Small Bear has disabled all purchases for a month as of EOD yesterday. I wish I had noticed this as I had the cart ready to go and sat on it.

Does anyone happen to know where I can get:
(5) BA282
(1) LM13600
(1) C150K pot
(1) 2-position DIP Switch

This is what I had in my SBE cart. It's such a bummer because I already sent in my Tayda order right before I realized this.

Thanks again.
