6L6 SE Tube Amp Kit on eBay... opinions?

[bermtoog]

I was surprised to see that no information can be found on the forum because there are over 6000 hits on this auction: 6L6 SE Tube Amplifier Full Kit (12AX7 and 6L6GC) Stereo | eBay

I am looking to build my first amp and I am interested in the sub $300 range. I have ~96-98 dB speakers (Audio Nirvana full range) and the 6-10 watt range is what I am aiming for.

Looking for something with purity, warm midrange, and very few additives to the original signal. I will be using a sub/sub-amp for the lows below 100Hz.

Has anyone ever used this amp or could someone speak to the quality possibility based on the components/schematics in the auction (and perhaps speak as to why for my and other readers edification)? I am a newbie to amp design but a veteran to audio and sound in general.

Thank you for your time.

Consider the amp in my signature. A lot more expensive, it is a COMPLETE kit, and originates from the US, and I am only an email away.

FYI: OT primary inductance, 58 Henry

Thank you... the amp looks great and probably sounds even better but there is no possible way the wife would agree to 850.

Also, were you saying the OT should be 58H?

Not necessarily, however the primary inductance of this particular transformer design provides for an excellent low frequency response and it has excellent high frequency performance as well.

Thanks,

by the time you change all the not so good components out, you could have build a better amp from scratch.

and besides point to point if done correctly outperforms the same circuit on a pc board in side by side comparisons. And its more adventureous and gradifying when your done.

Thanks Scott, that is certainly helpful and something I will keep in mind in the future.

Which components in particular are "not so good"? Also, are you saying I could build this same amp by sourcing higher quality parts for less than they are selling for? If not, I am still under budget constraints.

counterfeit caps and the wrong series of dale resistors.

$7 6l6's $5 12ax7's

output transformers $40

power transformer $80

the only thing really worth keeping is the toroid, but that is debatable.

I would seriously recommend looking at the Tubelab Simple Single Ended ampSimple SE board. It is a printed circuit board but you should be able to source cheap transformers ant tubes to make a great amp at a reasonable cost. Plenty of people here have built the amp and the designer provides great support on the forum. There is a dedicated Tubelab section of this forum you should check out Tubelab - diyAudio.

Cheers

Thank you much Chrish, that site seems very informative and useful. I will probably end up going with their design. I searched all over the internet for a very long time and somehow I never came across that site.
