Amek TAC B2 Power Supply

[Matt Syson]

Hi
First off you need a tech who can actually FIX things. If it blows fuses then it is still faulty.
Secondly a 250 supply will not be happy with a 16/4/2, certainly not in the long term.
The 2 supplies are essentially the same but the 350 has extra power transistors, a larger mains transformer and a fan, in comparison to the 250.
You could conceivably 'uprate' a 250 to 350 by adding the extra components, replacing the transformer and adding the fan as the circuit board is the same, but it is probably easier and cheaper to get a whole new supply. These desks need plus and minus 17.5 Volts (16 - 18 acceptable) and 48 Volts for 'phantom'. This is similar to many alternative desk manufacturers.

Thanks allot Matt...I had a feeling it wouldnt work...I'll just try and get a tech to fix the 350 power supply correctly. Hopefully its not the mixing board that is causing the problem.
