This is a first time that I build a tube amp.
Did not all by myself, had a big help of my 12 year old son.
He did all soldering exempt connecting the transformers, and I was mostly busy with mechanical part.

First time connected to the mains and everything was working fine. A bit of hum and noise but 70% off sorted with proper grounding. No smoke no bang...

Sound is very clear but not really warm. Missing bass, and mid range sounds to strong.

A bit disappointed to be honest. So now, need action to be taken to try to rectifier that.

I was thinking to do something of that:
1. to order tone control unit
2. to try with equalizer
3. maybe new output transformers
4. or to build new tone control unit, but that means new power supply as well (all with tubes off course).

Any advice or comment would be greatly appreciated.

You might have already seen this, but if not, below are links to modifications made to coax better sound out of the S5 kits. The links are referring to the K12M kit, but most most mods could be applied to the K16LS kit with similar results, if properly executed.

gljiva, I have had emails from others who are not pleased with the K-16LS. It seems to have the same problems as the K-8LS. Here is another person unhappy with the k-16ls tube amp

Let us know how you make out.

Good Day,

Take some time today and connected laptop to k16.
Huge noise to sorted first by disconnecting laptop from mains. After that almost complete silence.
So back to business. Used winamp with equalizer preset on techno.
Must tell you result was perfect. Clear and soft sound. So far best results without messing around with tools.
Speakers I using are mission 773. See pictures:

One question, by the way. It is possible to attach more than one picture at a time or...?
