MHDT Orchid TUBE ROLLING

Interested in hearing about tube rolling experiences with the Orchid and other MHDT dacs, namely, the specific comparative sonic characteristics of the various 396a, 5670 and other compatible tubes used in the output buffer. My only experience is with the WE396a that Linear Tube Audio installed in my new Orchid.

BTW, A 5/64 Allen work perfectly. AND the WE396A JW tube sounds amazing right out of the box!

@pmboyd   Thanks. Yea I have bought from Brent in the past. Got my WE 396 D getter from him. Looks like he is out of stock on most of the tubes you mentioned. He has some of the E88CC / 6922 Siemens, West Germany made, 1960s wide getter support post, gold pins in stock. Might try those. Need to see if the “ the Getter support post” is a wider tube than what I’m currently using and if it will fit (with adapter) into my Orchid.
