Title: footswitch and pab and od switches not working Post by: pepperdog on February 21, 2010, 02:52:40 AM Hey guys its been a while but I've finally had some free time to try and solve this problem,but to no avail.To recap the amp works(all the pots ,the bright,deep,rock/jazz switches)and sounds great.But I cant get anything from the rear pab and od switches or the footswitch(no clicks,lights,ect),I checked all my voltages and they are spot on,and I did bias her.When I check the voltage to the small board next to the pt that the 6 volt wires go to I am getting that, and Iam assuming I should be getting that to the 2 wires that go to the footswitch connector,but Iam not?Also there are no voltages present on the relay boards either,but anyways anyone with some ideas?,thanks in adavance :'(

just a thought Title: Re: footswitch and pab and od switches not working Post by: pepperdog on February 21, 2010, 02:24:23 PM Jubeman,thanks.Ive rewired everything with no results.Ive got 16 volts dc to the left side of my voltage reg.middle is ground and nothing on the right side(that supplies the relays).Also no voltage to my relays whatsoever.Could i have a bad volt. reg.?

You got a malfunctioning voltage regulator. That's why you can't switch the relays.The right pin of the voltage regulator should give a exact 12v reading.

I cant wait to get this baby working right,thanks again

I cant wait to get this baby working right,thanks again You're welcome, don't know about radioshack I'm a EU guy. Voltage regulators are widely available at any elctronics supplier.Title: Re: footswitch and pab and od switches not working Post by: pepperdog on February 25, 2010, 01:08:55 AM Yep that was it.Now heres the funny thing,with no pedal installed the amp doesnt work unless the switches are on pedal(i realize this could just be the switches wired wrong) but with the pedal installed on pedal I get nothing from the amp unless I crank it and then its stilll barely nothing but if I engage the pedal it works fine.So basically it only works with the pedal engaged so i cant have a nice clean setting and then hit the pedal any idea's?sorry for the long ramble,thanks
