Anyone using KT88's in D series ARC gear?

Hi Lostbears, Thanks for the input. I think the two large Caps may need replacement as they are all original. The speaker strips seem designed for bare wire or? Anyhow, like you say they are a real problem. I will probably have someone replace those along with the cheap RCA's and the hardwired power cord.

Hi Lostbears and Rrog, Thanks for the info. I think it is wise not to modify the amp after what you have said. I too believe the amp is truly a classic and I agree with what you are saying.
I may send it to ARC for the repairs, although they are very pricey, so IF I can find a very good local tech who is familiar with these amps, I would prefer to go that way.
The smaller spades required for the speaker cable are proving a little more challenging, But hopefully I can find a supplier of these. Again thanks for the help.

Hi Esporma, I solved the barrier strip problem by using bi-wire pairs of Nordost Red Dawn. The Nordost factory terminated the amp end with a narrow spade that works well with the ARC. BTW, I still believe that these amps are a PHENOM
BARGAIN at the price that they are selling for currently. No other amp or even any other piece of kit even comes close to this kind of a deal. I really do NOT understand why these amps are frankly been given away at this time.
