My Holton amp builds.

[Leikis]

Looks even better

Hows it sounding?

So far so good, but its just getting warm
My Infinity RS1 isnt realy suited for only 20watt. So the amp is out for a test against a DIY FirstWatt Aleph J later.

 

[Leikis]

Just to say, the 20L sound awsome. Its easy to get adickted.
And the gains dipswitch is realy good to match it to the rest of the system when using active crossowers ! Looking forward to test the 50L later ��

Inside the 20L

 

[Leikis]

I played a couple of days with the 20L on my Infinity RS1, supprised how good it sounded on them. Sensitivity is around 85-87db.
People ho is around for a class A amp, no need to look more. The 20L is the solution, ore the 50L if you looking for more power.
Realy hungre speakers ? Buy 4 50L. 2 boards for each channel when using xlr pre.
+ signal for one board and - signal to the other one and ground to both. 100 watt class A should make almost any speaker sing. But the wallet will hurt a bit ��

Thank you Leikis to show us your builds, they are amazing.

A while ago I ordered a 200L R3 module, the PCB-layout is a work of art, I can only imagine how much passion went into his products. I need to try them out.

New projeckt in order
Bridge 50L boards. 2 boards for one channel using xlr innput.
2 monoblocks with some pass look chassis.
Alot of Nichicon KW 2200uF 63 volt caps is ordered.
One special ordered toroid 630VA 2x25volt, built on 800VA core, can deliver totaly of 18 A.
For the innput 120VA 24volt.
Around 60 capacitor for each channel. Making 66000uF.

 

[Leikis]

Load with Nichicon KW 2200uF 63 volt. 250pc should be enough
