Last night tested the tubes in my B&K 707 and found slightly weak
V7 6EH5 the AF output but speaker sounds good V8 6HS6 Premixer V1 6BZ6 RF Amp All of these tubes test slightly weak but would this cause a sudden loss of muting ability?

In standby or ext mute (w/o short in RCA Mute)audio is distorted RF Gain only raises S Meter to 20 over or so. Something seems to have changed since I used it last a few weeks ago. Could this be a tube failing or ?? _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
