SOLD: Balanced Only Beta22 Worldwide Shipping  

post #1 of 40
Thread Starter 



Up for sale is my balanced Beta22, here’s the details:

It’s a headphone only build as such it has no speaker posts.
The input is XLR only, the headphone jacks are also XLR balanced only.

The psu is dual mono Sigma22 in it’s own par metal enclosure.
It features a very nice filtered IEC, the transformers are 50VA each.
2 Amphenol umbilical’s for left and right amp boards.

The amp is a 4 board build in it’s own par metal enclosure.
It features a DACT CT2 attenuator.
Wiring is 22awg teflon silver coated copper for signal and 18awg teflon silver coated copper for power.

The amp has preformed flawlessly since being built around 18 months ago. The build was very successful, not one component was de-soldered from a mistake or mishap, all soldered joints where meticulously made with great care. All boards achieve zero DC offset. The gain is set up for 2, a total of 4 as this is a balanced build.

$XXXXX AUD plus postage firm, this is less than I paid in parts alone.


Now $XXXXX + postage.

Pictures can be seen here:


International buyers I will convert the voltage over 120V if needed.

Moar pictures of John's b22 = WIN!

John selling his b22 = Noooooooooooooooooooooooo!


On a more serious note...

Having seen it, used it and talked with John about it in person, I can say that this is an extremely well put together amp.

The amp is surprisingly compact.

It looks like a lovely amplifier.
