3 watt ECL86 SE amp!!

Posted 12th May 2012 at 08:44 PM by hbc

It seems that random acquisitions seem to precede the direction of my inspirations. This has come in the form of a Technics SU-9011 pre amp and a pair of small infinite baffle 2 way speakers. I have no idea what they are, so please share if you do.

The active sony’s, to be honest have been getting me down, they still have a mushy quality to them. The SU-9011 seems to work but was not the happy match with them either. Enter the little 2 ways and my gain clone. Bad.

So I decided to try and power up a little EL86 record player amp which I acquired a few months ago from a friend. This seems to be a close relation to the Mullard economical 3 watt amplifier. To my slight surprise it is in good working order, so with a bit of drilling fitted some 4mm posts and some phono inputs.

With the little 2 ways and the Technics is a lovely combination, real bloom, very enjoyable, and some nice bass.
Technics has “opamps” in, so that gets me thinking of making a tube hybrid one to drop in as a replacement.....


I have found that so far adding bicycle puncture repair glue to the foam speaker surrounds holds them together.
