Keeley Katana - Surface Mount Alternative for 2N5458

[JDJudd]

Hi all - I'm trying my hand at PCB development and decided to start with a Keeley Katana Boost.

I've got the thing just about done, but the 2N5458 semiconductors aren't available at jlcpcb.

Any ideas?

This is why my layouts are a mix of SMD and through hole. JFETs present issues and lots of the cheapo 1uf (and above) polarized SMD caps are microphonic. Unless you want to order SMD fets separately and solder them yourself just make the jfet pads through hole, its less headache.

Solid advice. Thanks.

Now if I’d just not have tried to be clever and not mounted my 3pdt footswitch directly to the PCB, I’d be good to go! Those things are a little taller than PCB mounted pots. Ugh.

I’ve been meaning to buy some of the long pin pots to see if that will help, might have to fold my electro caps down for clearance. I’ve got a design with the 3pdt footswitch on the board too but I may rethink that one or just change it to relay bypass.

I'm looking at adding a cable/connector assembly to my next design to see if that will solve things.

I looked at those long-pin pots too. Just about pulled the trigger, but I've also got 3 toggle switches, so had to rethink it.

Hey, @Nostradoomus - I'm having trouble finding a cable/connector assembly that'll work. Have you tried using those before?

I've got 15 traces that need to jump from one board to the other.
