MRC AD 350 DECODER IN A PROTO 2000 GP 7

[Anonymous]

I HAVE INSTALLED AN MRC AD 350 DECODER IN MY PROTO 2000 GP 7.
LOCO IS PERFORMING VERY WELL, BUT IT BUZZES SPECIALLY AT SLOW SPEED
ANY HELP??

Not much you can do, the MRC decoder is NOT ‘silent running’ or "supersonic’ and so causes buzzing in certain types of motors.
If you want to keep costs down but still get quality, use NCE D13SR or TCS T1 decoders. The BEST solution for the P2K GP7 is the Digitrax DH163L0, it just plugs in, no need to fiddle with the light bulbs. If you are replacing the bulbs anyway, such as with LEDs, then the D13SR and T1 are far more cost effective.

Thaks for your prompt answer Randy. My problem is that living in Argentina sometimes implies to make ^^blind buying^^ since there is not a hobby shop offering DCC and advanced products. So I buy following MR advertising and my instint
Thank again. I will follow your idea for next buying

I have used the Digitrax DH163LO in a Proto GP9 and I am very pleased with it’s performance.

Good Luck,
