InfiniCaps in Audio Research gear

Maxgain, it has been a while and just visited the garage and the old SP3A-1 and see I used Wonder Wire for signal grounds, 22awg 99.9999 silver/w teflon for signal and some aircraft quality 18ga silver plated OFC w/special teflon (the kind that doesn't get brittle at low temps in aircraft) for DC, filaments and B+.....Had SP6s, SP-11s and SP-15s and they went away whereas the old SP3A-1 stays here as a reference.....Nice old piece that will beat up most anything made today in a number of ways.....

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.
