For classical orchestra, "Trittico" directed by Fennel.

"Still harry after all these years" will be for fusion jazz.

Any more suggestion gentlemen and ladies.

I'm using the 1980 1578 in the Atma-sphere gain stage with a Sylvania GTA in the 2nd stage. There's lots of high-end sparkle and air due to the GTA's excellent highs and mids.
That's why I haven't noticed a lack of extension with the 1980's.

@testpilot, there are no Melz 1970s to be found, but I'll continue to search.

Thanks, Greg. Sounds like a standup dealer, I'll contact him.

So far so good.  When I have a new pair of tubes that work properly, then I'll consider them a stand up dealer :)
