General Tso's Compressor Component Question ?

[Pimpoftheyear70]

Im starting to gather up all the components to build this compressor , and the BOM lists the BB OPA2134 op amp .
I have two (2) LM4562 op amps on hand left over from a Carver C1 preamp revamp/restore .

Would the the LM4562 Op amp work in this circuit ?
Would it be a suitable replacement for the BB OPA2134
Should i just get the OPA 2134 ?

Lay the wisdom on me !!

Thx

J113 ... Any other optional units that might work in that location ??

Have you checked the datasheets for the op amps to see if they are compatible? They are both supposed to be low noise high fidelity audio op amps, so it should not be to big of a difference. Although if you believe the mojo then the BB is supposed to be superior. As for the J113, try mouser, they have them in stock. Since this is just a buffer circuit, you can socket it and try a 2N5457, it should work for a buffer, that's if you don't want to order the J113. Just check data sheets for the pin outs and make sure you have it correct or it will not work (1 benefit of sockets).

The good old inxpensive TL072 is FET input just like OPA2134. Im running it in my optical compressor and it sounds great. I do have some of the OPA2134s but have not seen (heard) the need to swap it in
