Hi

Don't hold yr breath on Chinese-made tubes. Lower cost shorter life-span. No miracles !

Such 6-month short short warranty should have already hinted the consumers what would happen sooner or later.

FYI, the 50-plus-year-young Telefunken ECC83s & then-brand-new made-in-Geat-Brtain Mullard ECC82s used in my phono-preamp for some 7 years, operating quite many hours week-in week-out. They still make me good classical music - nooo problem.

Brandnames speak !

Ir's worth noting that a great many audio products are only warranted for 90 days until the warranty is extended when the product is registered with the manufacturer.Those warranty terms don't apply to tubes included with a product---
that six month warranty on tubes is the de facto standard---Chinese, Czech, Russian, whatever. The longest warranty I know of for tubes included in a product is one year, and that was only for the small signal tubes. I've seen power output tubes with as little as 90 day warranty coverage.

Hi

Really? So please name a few brandname audio products in the marketplace today only provide "90 days" warranty.

I am all ears

Hi

Guys, No politics in this open venue please.

As posted in Stereophile forums since day one a few years back, I am on 'quality" only.

While we are still on this tube amp, suppose you were the owner of this amp, just arrived & put on test run - it broke down in no time!
What woud you feel ? You would still love its design/quality control ?????

It could be built in the Silicon Valley, CA, or the Brazilian rain forests or whatever. It "happened" to be made-in-China ! This unfortunately reflects on the "ethnics" issue as seen by some politically knowledgeable readers here.

In fact, I fixed a few "high-end" tube power amps made-in-China, using bigboy tubes, e.g. 300B & 2A3 just within a few years & surely I know how good were those made-in-China were. Even after upgrading it with expensive audiophile-grade caps, interwiring etc etc as requested by their ownes, the upgraded sound quality did not impress me at all vs tube amps built in Japan/USA which I auditioned before.

I quote basing facts being an electrical engineering guy.

Hungarian music (Bartok string quartets) on my French, Canadian, German, Italian and British system.

Hi

I love Chinese ethnic cuisines bigtime, not those cheapie 'alien' chinese food in foodcourt takeawys or in foodcups !! Like tubes, money talks !!!

Yes, I pretty like Brahms' music, particularly his Violin Concerto in D Major. Soooo romantic !!

His Hungarian Dance No. 5 is also my favourite, not the other Dances though.

Listenig is believing

I noticed the Crazy Eddie reference or Easter Egg, does this reference "The Mote in God's Eye" by Larry Niven and Jerry Pournelle?
