Built my first plexi ?

Post by jamme61 » Tue May 08, 2018 2:11 pm

Built the 50 watt kit from valve storm plexi Kit 4 hole- everything is fine except low input jacks don't work just high input- I used shielded wire and put the 68 k on the pin 2 so it's not a stk input jack wiring - anyone have a diagram how to do this?
Thxs for any help

Post pics of the diagram you used to wire it up and pics of how you implemented it.

One of us will help you out.

I don't think both Input jacks (Hi & Low) can work based on the way you have the 68K resistors hooked up. The two 68K resistors need to form a 'Y' so it can connect the two Inputs (Hi & Low) together.

Well that will work if you are using a shielded wire from the junction points of the 68k to the socket, but I think you have built a 2204 the pre amp with only one pair of input jacks from your final pics?

That's the way it looks to me too. The 'cliffjacks.gif' picture shows the 68K resistors soldered at the jacks like Friedman does on some of his amps...By doing it this way your eliminating the green link wires normally seen and then you can use a piece of shielded cable from the junction of the two 68K resistors to the preamp socket.
