Willo,

I am one of the more technically challenged inmates, and Chris, kentaja, and the others have said it more substantively, but beginning in 1985, I have owned an SP8, SP10, and D115 and I cannot see the truth of the assertions of poor design leading to overstressed components in ARC equipment. My impression of tubes is that have long established standards and ratings- that even I can look up in a book- and who could remain in business selling $40,000 monoblocks if they didn't bother to look to these ratings?

When I made intelligent choices- ARC recommendations- this gear has been quite reliable and certainly show signs of the highest quality of design thought and construction. I have 9 pieces of tube stuff and the ARC glows with it's thick boards, traces, and substantial controls and high end components- and long tube life.

The SP8, while not in continous use, still has all it's tubes from 1985, the D115 it's original 6FQ7s, and the SP10 (1987) original 5881s. The D115 did arc a GE 6550, but I had pressed those tubes too far- almost 6 years- the D115 being my first tube amplifier. In 15 years with the D115, I am on only my third set of 6550s. The Amperex phono 7308s in my SP10 have been there for 8 years. The SP10 is quite difficult to find it's phono gain tubes as they are in a high performance situation, but I can call Leonard and appropriate tubes are waiting there in Minnesota.

High performance equipment does not suffer too much in the way of casual maintainence and I don't need a Textronix 570 to trace most all my ARC problems to me!

Cheers,

Bambi B

I would be willing to say that about VTL, but not Audio Research. - M_Anker 04:52:23 04/08/03 (0)
