Mac97 Triac??

[9Lives]

Hey everyone. I'm still working on my amp. The peavy prowler. I've replaced all the tubes will JJ hi gain 12ax7 and matvhed 6L6GC and fixed up the jacks, lubed all the pots and it's back to life. The last problem (that I know of) is the remote channel selector. I understand that in order to remote select the switch ON the amp has to be engaged. I have the boost working with TIP and SLEEVE connected through an Led. The RING and SLEEVE are supposed to switch channels but it doesn't work. It goes through a mac97 triac which I'm not very knowledgeable about. It's a diode with an extra anode like a gate? That runs through a p channel Jfet J174. When I touch the TIP to the RING it also switches the boost which makes me think it might be grounded or shorted. Are these mac97 prone to this? And if I go ahead and change rhe jfet with 2n5460 (ithink) will this work? If you need a schem I can email. I don't know how to post the pic.
