L12-2 kits

[Tarasque]

Have a couple of L12-2 kits. Have constructed quite a number of these kits over the last years and all worked flawlessly.

Have some kits left and willing to sell these for 12 euro each channel. That is PCB + ALL components.

Shipping and paypal fee is extra.

Sounds good!
Can you use 2 of them for balanced input?

 

[Tarasque]

Yes! 2 amplifiers driven via ballanced input works well when wired correctly. This doubles the output power as well. It also cancels distortion by a factor of 5 to 10.

 

[baggerbole]

Ok, if you tell me the correct wiring for balanced I´m in for 4 kits

 

[Tarasque]

Just minimize the area inside power traces/ cables and keep away from ground loops. Reduce the supply voltage to 30v or less when driving 4ohms or less in ballanced mode.

Shipping to germany is 9 euro and paypal fee is 2 euro.

Bernd, James...Your shipments should arrive any day now

Arrived! Many thanks

Hi Marc,
parcel arrived yesterday. Thanks!
Interestingly packaged
Can you post a schematic and a small hand sketch how to connect the amps balanced please?

Cheers
Bernd

How does this amp perform soundwise ?

 

[Tarasque]

With the power supply I used, I like the sound very mutch. I've build and listened to quite a lot of amps and this one really delivers. I dare to say you won't find a better amp for this kind of money.

wired like this?
How to cennect the in/out grounds?

 

[Tarasque]

 

[Tarasque]

Within the amplifier the grounds are connected (VOED). The ground of the XSLR CAN be connected but is not required as the output of each half is regulated against the connected grounds. I have inserted ground lift in the XLR ground as well as one of the Cinch connecters. when the unit is in use as stereo amp you need to connect al least ine of the grounds of the cable.

Hello,
Is there a couble of kits left?
Thank you in advance

 

[Tarasque]

There are 28 kits left. How many would you like?

 

[Oracle1]

2 for a stereo amp

 

[RTBNL]

Over a year old,are there still some left?
