Mahayana IC

[huntest]

The more I read about an IC for my Mahayana build, the more confused I get.

There seems to be a number of substitutes for the AD712 IC and since I will be using a socket I can try different options. I've looked at Digikey and Mouser and I can't decide which to try. Suggestions and advice please.

Also would appreciate suggestions and advice on which transistors to use.

Thanks a bunch

This is what I typically put in them.. Kinda spendy .. Plain ole TL072 works fine too

I'm going to go with the OPA 2134. I'll use a socket so I can have some flexibility.

Always go with the sockets in the case of ICs. Nobody needs the stress desoldering an IC.
The OPA2134 is maybe a bit overkill in an overdrive, but at that time the Hermida was developed they still were affordable.

Swelchy,
Are you referring to the TL072 IP or the TL072 CP for the Mahayana IC build?
Thanks

My OPA 2134 IC from Stompbox parts came to badly smashed. I hope they replace it.

Even if I tried to straighten the legs, the chip is surely damaged

TL072
LF353
NE5532
LM1458
4558

literally any dual opamp will work. (personally i wouldn't bother with the OPA2134 for a drive circuit)

as mentioned above, if you use an 8-pin IC socket (or build the circuit on a breadboard) you can then audition any one of these opamps to determine which you like the sound of the most.

Also would appreciate suggestions and advice on which transistors to use.

build doc specifies 2N7000:

tayda has them.

Any preferred versions to these?
