6J2 tube rolling?

Ordered some RCA 5725’s off eBay, hope they fit lol 

How’d we get from replacement tubes for a cheap side project to $500 tube phono pre’s 😂

different tubes I know, just think they are worth considering, if only to spark questions

another versatile unit

not knowing your budget, I hopped about on eBay, see what's interesting,

this unit is very simple appearance, but read the notes, very versatile for MM, MC HO, MC LO
you would be set for most future cartridge choices

I generally use a NAD PP-3, but was considering picking up the well liked ChiFi Fosi tube phono pre just for fun to see what it sounds like. Not a big investment.

@dougeyjones   Just curious, which phono pre do you have that utilizes those tubes?

You can use any 6AS6 or 5725. These are unfortunately not very common tubes so there will not be a lot of choices.
