JJ243 Pre-Amp - impressions please


I am looking at valve pre-amps below $2000.
This JJ243 is one suggested - has anyone got any information or experience with it?

Thanx

For right around $2K and maybe just a bit under if you keep an eye out, try a Herron VTSP 1A, I have one and think it's just fantastic, as good a preamp as I've heard, as well as dead quiet and reliable.
I have a jj 243 purchased from Audiogon for $675 so I cannot complain,it sounds fantastic with my turntable it is adjustable for gain and I have not had any heating problems but it must be well ventilated as the one I have is.I will not be looking for a pre for a long time.There may be pre amps just as good or better for the price but it sounds fantastic to me smooth with good bass not tubby with a nice detailed midrange but not to forward with good balance in relation to the bass and treble.Turn it off when not in use and things should be ok takes about 45 minutes to warm up.
I have had a JJ243 for over 10 years and never (knock on wood) had a problem with it.  goes great with my Beogram 8000.

Since I don't use it much anymore I will soon be entertaining offers on it.  It is in immaculate condition, no scratches or nicks, comes with original box/carton and Manual.

Thank you
