why so CHEAP!?
since im building a pair of fullrangers soon, ive been looking at tube amplifiers. Now i dont know about you, but when i think tube amplifier, my wallet starts screaming. but i was looking on ebay and there are all these tube amps from hong kong going at REDICULOUSLY low prices, below are some examples...

how can they sell this stuff so CHEAP? the machined parts, chassis, and tubes must cost close to that much! i did notice that they nail you on shipping, but still, something MUST be amiss.

They saved big time on CSA approval? ;)

They are made in Shenzhen, China, I'm sure.

From one very credible review I read once, they aren't bad at all. Caps and such might need being upgraded. But the thing, according to the reviewer, is that the built is there making upgrade/modification worthwhile.

Edit: Just googled this: "Located at the southern coastal area of Guangdong Province, Shenzhen is a Special Economic Zone and important industrial base in China, with an area of 2,021 square kilometers and a population of 0.8 million."

im really eyeing up that kt88 one, it looks so sleek, and it may not have much power, but how much pwoer do you really need for a pair of FE166e? not much!

Yeah, it looks very neat. Those tiny handles!

I don't put much faith in Watt ratings. But 12 class A Watts aren't little.

probably mroe than enough for what it woudl be driving.

what do you think woudl sound better? that kt88 amp or a super t amp?

i know that the tubes would be a fair bit louder and offer more headroom.

ahhhh never mind, when you look at the buy it now prices the cheaper ones are about 500$, and all of the other ones that people have bid on, havnt had the reserve price met yet.

too quick on the trigger i guess:(

looks like theres a super t amp in my future

I've dealt with that vendor, and he's quite good.

Good amps, I heard the one with 300B.

Re: why so CHEAP!?
Yeah, sure, 37 Watts per channel claimed out of a pair of EL34 per channel, running in "pure class A" ... either this dude thinks his customers are stupid, or he himself doesn´t know better - neither being a good sign :mad:

Theoretical maximum class A push pull efficiency: 50%. Max Pd of a pair of EL34: 50 Watt. ==> Theoretical max Po / ch: 25 Watt. In real life, you will have a hard time squeezing 20 class A Watts out in pentode mode.

AISI, this is not a serious offer.

These are China's inexpensive tubeamps.

Their output transformer does not good.They produce from Wenzhou,Zhejiang Province .

The hope does not purchase

Moreover,China has very many outstanding products,Like "audio01","Xindake","oper","shanling".They are China's outstanding brand
