A picture of my tubes...

I agree with Bob that the Valvo and Brimar are two of the best. On my system they both have very nice highs and excellent soundstage, I prefer the Valvo slightly because I find the Brimar to be a little bass heavy for some material. My impressions of the Mullard are almost exactly as Bob...

Thanks for doing this Don, this is a great gesture and Alex really does deserve it!

Why don't you try the 8416's first? The mod is very easy, no cathode resistor change and runs good on stock power suppy. swap a couple of wires, plug them in and listen. If you like them add a resistor to fine tune the voltage, it won't hurt them to run at a higher voltage for a short time.

I have been using 8416's for a while now and I really like them but I can't compare them to 6N1P's because I haven't tried them yet. I plan on doing Regal's mod in the near future then I will give them a shot.

I'll take one set!

Has anyone got around to trying the OPA827 or OPA2211 in their Ivy yet?

Excellent review Adamus! I hope you enjoy those 8416's as much as I do. For output caps you could go FT-3 russian teflons off of ebay.

Looks good to me, mine is quite a bit tighter and no noise problems.
