Re-tubing my ARC reference 1 preamp

I recently retubed my ARC Ref.1 with the 6H23's from Upscale and have been very happy. These tubes are quiet with great bass and midrange. I previously used NOS Amperex tubes purchased from ebay with mixed success. Many of them were noisy and produced microphonics. There is no such problem with the 6H23's.

Slates, I think you have a good starting point. The 6H23s are only $15, so you can try and decide.

Thanks Everyone , I know I could count on you.

A friend of mine is going to let me borrow his Mullard 6922 Gold pin,
he says if like them he will sell them to me.

You will get warmth with those Mullards. Good sources for NOS in my experience have been Brent Jesse and Vintage Tube Services. Hardes part is getting closely matched and balanced pairs, but these guys seems to do a good job.
