Tube Suggestions Onix SP3

As a rookie to tubes, one of the Melody 5881s tubes on the Onix SP3 I recently purchased on Agon has gone pzzzsst and I'm clueless and suffering without good sound. I have to keep within a reasonable budget but at the same time have a solid replacement for resale value. Can the original Melody 5881's be had anywhere? Otherwise the tube shop I called said I need to replace all four, rather than only 1 and recommended the NOS Sylvannia 5881 at nearly $90 per. I'm tempted to just buy another used Onix if that's the case. (Just kidding) Help

Will do Newbee . . . it's an odd comfort to know this is somewhat common. I will do the shop . shopping. Any suggestions for a repair facility would be greatly appreciated, as I have not had work done prior to this?

I received the SED 6L6GC tubes and installed. On immediate listening they seem much more harsh on female vocals than the original Melody tubes. Almost to the point of sounding like clipping. Could this result from no burn in time yet? It was as if I hooked up an inexpensive receiver, nothing close to the original sound. Do I need to change some settings on the Onix? I've heard others talk about bias but not sure if this is possible on this Amp. (No Manual came with it) Any suggestions would be helpful.

Outstanding Tooter, Rhing and Newbee. Left a message with av123 checking on the replacement Melody as a plan B. I will work on the Bias per your instructions Tooter. Much Appreciation All.

Now there's more than one explanation for the distortion! On the right rear test the reading is 10.55 and won't go any lower. That's also the one that blew. I don't know much about this but something tells me I bought an amp from an Agoner with a bad 'wheel'. Can this be repaired or replaced in anyway? I'm O for 2 on Agon buys now - but with the great help from you guys I still have faith.

Any suggestions or should I post this as a new thread?

I ran the test again before and after switching tubes and the reading actually went up to 11.23.

The rest are holding fine. Any idea what part is the contibuting factor? I will try av123 on Monday. I haven't had success getting an answer via email from them yet on finding the original tubes from Melody.

Thank you

Thanks for the post Tubeears. Here's an update with outstanding news. I contacted John at av123 and they are replacing my amp . . . that's how to stand behind your product! Can't say the same for my CD. I was so thrilled by the Customer Service at AV123 I went on-line and bought a sub-woofer. Now if only all the dealer/distributors would back up their product to secondary buyers like me.
