FS: β22 + σ22 balanced preamp/head amp SOLD
Will Ship To: Anywhere
SOLD to vtsai
My own project, which I completed some time ago. It a nice company for my β24 mono blocks.
It has been functioning perfectly mostly as a preamp.
All hi quality components used:
- Elna/Wima caps
- DACT source selector
- stepped attenuator
- neutrik XLR and very nice RCA
- pure silver and copper silver plated wires
- WBT silver solder
- FPE front panel
As you can see from pictures is rather unusual built, which is balanced, single ended and with another active ground for headphones.
Three channels seats on ε22 backplane board. Another two are positioned vertically on sides walls of enclosure.
There are also oversize heatsinks installed on all boards. Part of the reason I chose to go with bigger heatsinks is to compensate for it's horizontal placement on vertical boards.
Power supply unit contains two σ22(30V) boards with two Avel Lindberg transformers. One 80VA for two β22 boards and the other one is 120VA for three β22 boards.
There is also ε24 power switch with Bulgin blue button.
And finally gain is set 2x for SE and 4x for balanced. This gain proved to be fine with my Beyerdynamic DT880 and also larger numbers of amplifiers.
I've been very, very rarely listening to headphones since I switched to full size system with different commercial preamp.
Also I plan to build another, lighter version of B22 pre/head/amp from scratch. That's the reason I'm selling this one.
Any questions, comments etc... I'll gladly answer.
The amp can be auditioned in NJ 07407.
Pick up is fine with me.
Shipping charges will depend from location.
Payment by paypal (+3%) or cash at pickup.
Price = 1250USD or best offer. SOLD.
I'll also be listing the amp on ebay, where you can check my feedback. Auction link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110607147293
Just to answer a question i've received regarding input selector: angular step of DACT selector is different than indicators on front panel would require. Selector knob "click" will not line up with corresponding number of input on panel.
Printed numbers on front panel can easily be removed with sugar cube :-) (as I read on diyenclosure forum). Also, switch is 5 step type, so it make one position unoccupied (1 is balanced(XLR), 2-4 is SE(RCA connectors).
