Help With Buzzing Sound

Hi , sorry to hear you have an issue.  Off topic but possibly helpful. I recently had an issue with one of my tube mono blocs. At 55 lbs I feel your pain for shipping cost. When I sent my amp for repair I decided to send both. The culprit was a resistor on the phase tube circuit, but they diagnosed tired diodes in the power supply sections of BOTH amps. The other amp sounded fine and I guess until I had a failure I would not have known. I used Pirate Ship at the recommendation of the manufacturer and that eased the sting a bit. Also I’d like to compliment you on your listing room and appreciate the details you posted as I’m looking at acoustic treatments and building my own rack. Thank you for taking the effort to share your hard work. Respectfully, Mike B. 

@buellrider97   Thanks Mike.  I did a very long post a few years ago on building my system. (link on my virtual system) Creeping up on 10,000 views, and garnered some very nice comments.  I'm going to do another words & pictures post on the construction of my new listening room, that was part of a basement development.  

On the buzz issue, I'm a bit embarrassed to say I think it has been resolved.  This morning I took another run at it, just to be sure I had covered every base.  The last thing was to reverse the XLR cables at the preamp to see if the problem was cable specific.  Buzz gone.  Put the cables back in their right place and the buzz is still gone.  So, the culprit seems to be a slightly loose connection with one XLR cable?  When all else has been eliminated, the remaining solution is correct regardless of how unlikely?  Or something like that.  Anyways, thanks again to everyone who pitched in.  Your repeated suggestion to check the connections made me go back to that.  Cheers.

I’m glad it’s resolved without a repair. I can’t take credit for the suggestion as it came from another member. However sharing your experience certainly enlightens me to something I would have overlooked. Regards , Mike B. 

Congratulations on being forthcoming with your find.  We can all learn from your experience.

Let's hear it for a 19 hr cure!

Cable crawls are such a bore... ;)

...but it's certainly cheaper than the 'coulda' beens...👍😊
