FYI --
 
One of my sources for the United Electronics USAF-596 just turned up more stock, after being sold out for nearly 8-10 months. Will learn quantity, price and vintage tomorrow.

I recently received a new Woo Audio GES and SR-507. I notice a slight low frequency hum that appears to be volume independent and impossible to hear while music is playing. Between tracks it is definitely noticeable. I tried isolating what may be causing this hum by disconnecting the amp from my source, moving it onto a separate table, using a cheater plug and the hum was still present. I would like to see if there is anything else I could possibly try before sending an email to Woo Audio. Would replacing the no-name stock 6S4 power tubes have any effect? Besides this minor issue the amp is perfect and I would dread having to ship it back. I even have quad matched Mullard 12ax7 reissue tubes coming in next week that I can't wait to try out. I am new to tube amps so all of this is a little intimidating and any help would be appreciated.
