Has anyboyd used this amp, your thoughts on it

Yeah they're a Gamble unless you can find a thread here a thread on hifi.org or somewhere where someone's bought one and there's a bunch of people following it in a thread that's probably the only way I would buy one and I actually have found one.

I did find a 709 B amplifier it's a headphone amp / preamp it had about a 40 page following number of years ago but it seems like a good amp and it's been updated I actually purchased it.

I appreciate everybody's input a lot of choices obviously I actually bought a it's a 708 B headphone/ preamp.  What I'm looking for is now some help with E88CC tubes anybody here have any experience with these tubes I'm looking for some good sounding models RCA Mullard anybody have any experience with these?

Read the sound description at Brent Jesse. My personal preference is all nos stuff. My favorite is Tekefunken, Tungsram, Seimens, Ei. American tubes are 6922, Phillips, Rca, etc. The various Russian tubes are nice too. Personally I dislike Mullard , but others love them. The bottom line is you’ll have to try some. Maybe I’ll see you at a Tube Addicts Anonymous Meeting, it’s a vicious disease. 😆 Happy hunting , Mike. 

I will see you at the Tube Addicts meeting ha ha.  What you said though, the Tekefunken name keeps coming up and Seimens, there pricey tubes.  Thanks for you input.
