Audio Research vt100mkll question

I wonder if someone has experince of this ??

Two questions really.

I've just bought a vt100 mkll and am running it with single ended input from the source , with-out the pins in the balanced input. It seems to work ok just wondered if there was any down side to this ?? Should it work at all ??

Also My amp has been re-valved with 6h30's instead of the original 6922s. Is this a good thing as the 6922's are a lot less current hungry than the 6h30's ?? Will it work properly ??

Over-all the amp is proving harsher than I expected on leading edge vocals and sounding a touch bright. (could the valve be causing this ??) I'm driving proac 3.8s . Bass is good and some things sound very, very good.

Any opinions would be appreciated.

Thanks for your time.

Final update...............................

Every thing turned out fine in the end. I've had my amp in with a fantastic Auckland based Technician who has replaced my burned out resisters and set everything up for me. The amp now sounds great. It cost me about $60 to get done I'm super happy. :-).

The things I've learned from this are :

1. JJ EC88's do not work in a setup where they are mounted horizontally eg ARC vt100.

2. Always take out the 6550's when adjusting the pre-tubes. This can potentially save you dollars in the long run.

I'm moving into new house soon and I'm looking forward to setting up my room. In the end I've really enjoyed the whole experience (other than the burning out/ blowing up the screen resisters).

Thanks everyone for your advice and help.

Myron.

Borg:

I am happy for you. As I had suggested the resistors were the culprit.
The VT100 MKII is a fabulous sounding amp with surprising power. Enjoy
