Which tubes for Wavac MD805m

Thank you Cyclonicman. I have contacted the manufacturer and have been informed that the original input tube is the 12AX7. So now I can narrow my search on characteristics of different 12AX7 tubes. Is it worthwhile to go for the NOS Mullard or Telefunken tubes?

I don't think you can go wrong with either one. At one time, I had used both but that was in my preamp and either will deliver excellent quality sound. The Telefunken seemed to have sweeter high's, but both produce excellent mid range sonics. Nos tubes are very expensive and sometimes don't last too long, but I felt they were worth it. I am just not sure if the sound quality is as apparent when used in a power amp. I also found the Amperex bugle boy to be a good tube as well. Enjoy the journey!

I dont know, but my dealer suggested NOT to change the tubes on the 805 cause I would ruin the sound!

I replaced the stock with United 805s. Sounded much better. Tighter and more transparent!

This is an old thread but....
The best 805 is the Amprex 805, unless you can find couple of WE331A?

The 12AX7WA, say Mazda FSE are lovely.
I am as yet to try tube rolling for the 6Y6g..tubes
