HEY everyone haven't been on Z Talk in a while, however I'm doing a new Band Project that Screams SRZ!!!! ROCK< ROCK> ROCK!!! 60's to Modern so... I fired up the SRZ at rehearsal and after about 45 mins of playing I kept noticing a fizzy sound and some slight drop in volume..... ? at break I placed it in standby fired back up and again same amount of time it started again, I thought it was maybe a cord, speaker, inst??? took it home didn't check til last night checked the EL34 Mullards 33.5 and 36.2 Ma on the bias Voltage was around 462. I thought well I don't want to fry or damage my Holy Grail of 34's so I swapped them out for a Nice pair of Vintage RCA 6CA7's Because I didn't have a matched set of 77's set it to about 36 Ma Volts around 459 fired up Bam Sounded KILLLER!!! I was rocking it out! all )'s about 15 mins in it started the above problem then totally went DEAD SILENT!? WTF I thought I checked the RCA's I had NOTHING! NO VOLTS , after checking the usual starting point 120V in I found the 1/2 amp Fuse BLOWN? What does this operate? What Can I check ? Im leaning towards REC Tube? But I didn't have a 1/2 Fuse to replace the blown one so I haven't checked that, Any help would be so GREATLY APPRECIATED , I have had this amp for almost 15 years and never once a bit of problem, Its my #1 Baby! Thanks Jamie

Sounds like the Rectifier to me Jamie... That fuse is pretty easy to find as well. Even Home Depot carries them...

THANKS TO ALL MY SMART Z BROTHERS!!!!! It was the rec tube! I had a early 60's bug bottle GZ-34 Black Plate Sylvania in there It is now running a Sovtek 5AR4 cause it was Brand new. It sounds Like a Brand New SRZ!!!! I have several rec options , Is it Ok to run a 5V4? That's what I run in my Super it sounds KILLER! Thanks again, I cant wait to put my SRZ to work , I always get so many compliments on my tone when its on the stages. I'm saving for another Z Right now I'll be posting in another section coming soon!
