  • More Penta III issues

    Hi, More strange Penta behaviour.. I replaced a few caps in the amp board and it seemed fine again for all of that evening. Next morning I switched on and it was no longer working - I suspect a transistor may have failed so I'm ordering a new board (not ready for ICE just yet...) Does anyone know how the input mode switch is supposed to work? On

    I replaced a few capacitors in the amplifier circuit and fired it up - strangely at first the amp was behaving the same as before, a mere whisper coming through the speaker - then after a minute or so the volume began to fluctuate randomly through whisper to full volume and then it appears to have stabilised after maybe 5-10 minutes operation. Do new

    Bulgarien, Thanks for your encouragement, but US$560 per speaker for ICE is um, not so cheap a fix for me right now - have to get over buying the Pentas first! Steve

    Nick, Sounds interesting, but wouldn't that suggest that the green light would not come on? Also, there is some very low volume sound coming through. I still have the thing in pieces, so I will certainly check the relay. Steve

    Thanks Bulgarien, No, I have checked the fuses and they are fine... Do you have an idea which cap is likely to fail? I was thinking of doing the upgrade you suggested in another thread... ICEpower sounds interesting, will look into it and then probably have a heap of questions :) Still, for the time being I wouldn't mind trying to fix what I've

  • Penta amp failure

    Hi, I very recently purchased a pair of Penta III type 6631. They have been working fine since Sunday and I came home this evening and one has stopped working... It does not appear any particular event has occurred, I just switched on the beocenter and there is only one channel - checked the passives on the MCL and all fine. I checked the powerlink

  • MCL "sensor" eye?

    Hi, Is anybody able to tell me about a MCL "sensor" unit I received today with an MCL2A kit? It looks identical to the usual grey rectangular transceiver, but it does not have the Timer and Mute buttons - it is instead simply labeled "sensor" and the cable is a 4-core with a 6 pin DIN plug on the end...? What is this designed to

    Nevermind - I triple checked connections and there was a faulty solder on the data pin at the MCL 3 pin speaker plug... All working correctly now!

  • MCL2A problems

    Hi all, This is my first post - after searching the wealth of info on this forum, and several hours of frustration fiddling with a new MCL setup, I hope someone may be able to help! I have a BC9500 which I am hooking up with MCL2A kits in two other rooms. Checked and double checked all wiring, disconnected each MCL relay box in turn, and tried replacing
