The Manual and the back panel say to set the bias at 100mV and the Balance at 0mV. So Go to set the Bias and it comes up -100mV. Is it the same either way? Or Is there a Problem? Also it does not say But I am guessing the center connection that is used for both settings is common?

Any Help would be appreciated

Bass Amps & Effects / Tube retainers
« on: May 01, 2017, 08:55:29 AM »
I have a Fender Bassman 300 PRO it currently has 6550's in it . I am changing them out for KT-88's soon. My Question is will the spring retainers that are currently in the amp work with the KT-88'S or do I need to order some Bear Trap type retainers?

Thanks in advance

I have a Used Traynor Yba-300 It had some initial noise Issues when I got it . I changed out the pre tubes and it went away, For a while. After about a month it started making the noise again after it warms up about 20 minutes or so. Got brand new JJ pre tubes and it was quiet again for a few weeks but now it is back after it warms up. Any Ideas and it is only with the gain turned up. If I keep the gain down low it is quiet.

   Thanks in advance

Bass Amps & Effects / Ampeg V3 For Bass? Is it designed around the B25B amp?

I have a line on an Ampeg V-3 and want to know if it is voiced right for Bass and if it is worth picking up?

 Hi I just picked up a MusicMan HD 130 Bass Head. The previous owner had installes New EL34B tubes in it (About two weeks ago) but has not had it Bisaed. I Have Biased My Ampeg SVT's before with no Issues. Just wondering what the procedure on this amp is and what voltages am I looking for. . Also if anyone knows where I can find a copy of the manual that information would also be appreciated.

Bass Amps & Effects / Ampeg Svt Question (hum)
« on: July 09, 2010, 09:17:29 PM »
 I have a 75 SVT and the hum is getting out of hand and the hum balance does nothing to help. So am I looking at a recap job or does anyone have any other Ideas?   Does this need to go into the shop?
