InfiniCaps in Audio Research gear

Thanks Rcrump.

My brother still has a 3a1. I used it in my system for a while years ago back in the 70's. It's a classic is every sense of the word. I have had the SP5, 8 and 9.

Max,

I just rather have someone local do the job. Also, Gary is an ARC certified technician. The only one I know of in LA. Regarding dufus, I did look him up, but I gave up on pursuing it.

Let me know how the aftermarket powercords work out in the future k?

I have been told by a respected Audio Research repair expert that infinicaps were used as opposed to oil based caps. or other choices partly because of size consideratiions. That being said, I have had Classic 150 monos upgraded to infinicaps by ARC. I am pleased with the results. It is not a radical difference, but the music sounds more dynamic. I still prefer this unit to newer models.

Jwin are the VT series amps less tube like to your ear? I have a VT50 but have never heard the Classic60. The VT works very well in my system(uses 1/2 the output tubes as well) and I like the SS like bass controll. I have a med size room with a speaker system that can generate alot of bass energy. I had a VT60 prior to this amp amd it had a bit of an overly warm mid bass hump that didn't work as well for the combo. The bass is very layered and smooth with the VT. ARC has made many great sounding units over the years and if you have something you like keep it and enjoy, as I have done with my SP9, I just tweek it here and there along the way as you did with the 150's.

Maxgain, the Classic 150s have fet inputs and 6550C outputs. The solid state inputs help provide for considerably enhanced base compared to most other tube amplifiers. I haven't looked into updating the imput fets.
