    The best 12AX7's and 12AU7's for SVT 3-PRO

    Washburn Club!

    I have a metallic red B-10 I've owned for around 20 years, my first proper bass and I still gig with it. Playing metal so the pointed headstock is not a problem, it's a great workhorse instrument.

    SVT-3 Pro Service Manual

    I can send you preamp and power amp schematics if you pm me an email address, they exceed 150kb so I cannot attach them to this post.

    Ampeg SVT-3 repair advice

    Thanks for all the advice, it was a fantastic help. I took the amp to a tech who looked at the amp for 10 seconds and said he needed to replace all the Mosfets and it would cost £180 ($290). I then showed him what Jerrold had written but he was still sure the Mosfets were the problem so I...

    Ampeg SVT-3 Pro, advice wanted

    Thanks Jerrold, I tried plugging in and out the footswitch jack but that did not cause any problems. How can I check the drive to the switch circuit, it would make sense if this switched on and off repeatedly when the problem occured. Do I need to remove the PCBs from the case and inspect them...

    Ampeg SVT-3 Pro, advice wanted

    Thanks for the suggestions. The problem occurs when the amp is idle and also when I am playing. I opened up the amp tried gently moving the body of the EQ switch to see if it had a bad solder joint (it is PCB mounted) but it is fine, moving the switch button side to side also did nothing. I...

    Ampeg SVT-3 Pro, advice wanted

    I have had a SVT-3 for 2 years and am very happy with the sound and it is easily loud enough for me. The problem is the graphic eq sometimes switches on and off repeatedly on it's own, causing the sound to go louder and quieter, and the eq light flashes on and off. I have the eq level at...
