Title: KT170 tube...
Post by: P.I. on January 30, 2022, 09:16:05 PM
Does anyone know of a SE amplifier design using this brute of a tube?

Curious why that tube?  At $200 each, seems like a ridiculously expensive option??

The WE 300B is is $425.00

NOS 300B are $2500.00 a pop!

The KT170 should put out a lot more power than the SE KT150 amp I heard that sounded glorious.  Run conservatively it should last a very long time.

So are these so very much better sounding than, say a 6bq5, or the 6L6 family?  You're talking about an order of magnitude in price difference.

Hi Dave,

I've never heard of this company before, but this is one: https://www.tektron-italia.com/en/products/tk-two-kt170-pse/

Single ended parallel?

Looks to be lovingly and smartly built.  I wonder: how much?   8)

Thanks, Paul!

According to their FB page, it is €6,150.00. But, I do love the copper top plate and the wooden accents.

I better look someplace else for my tube amplifier fix until I win the Publisher's Clearing House weekly draw...

That reminds me of a joke:
Guy goes home and asks his wife what she would do if he won the lottery.
She says "I'd take half and leave your miserable ass."
He says great, I just won twelve bucks, here's six, keep in touch.
You guys and your tubes. Cool looking amp though.

Getting into a good confrontation with you concerning audio would be like me taking the tweezers from my knife to a gun fight.
