Quad Help!

[symon]

To be honest - I opened it up, looked in and thought 'Nope, no idea what this all means'

[spendorman]

Cant really see the wiring for the added pots, but let us assume that they work. Were they turned right up, down or in the middle? Obviously right down, one would probably not hear much from the amp.

Cant quite see if power limiter resistors are in they would be in two holes in each channel, marked R11 between the holes. This resistor just pushes into the two holes.

[spendorman]

This is a 405 board, probably a later production than yours. The limiter resistor is indicated in the circle. They just push in. Nothing in the holes gives full 100W/ channel.

[symon]

Nope - two holes unoccupied, so the limiters aren't in. And, I don't have them.

The extra pots are turned up full. They do have an effect, but nothing special at the moment. They just make a quiet sound slightly less quiet.

[symon]

I can't see how I would connect anything other than the 33 to the 405. I'm assuming this is beause of the extra volume pots.

[spendorman]

The resistors are just standard resistors, forget the value, one can tell from the colour codes (I forget the codes!) will probably be in the Quad instructions though.

So unless anyone has any other ideas, check out the 4 pin to 4 pin Din lead. Make or get a cable to connect 405 direct to CD.

R11 is power limiter resistor 1.8 K Ohm two needed of course.

[spendorman]

Just seen a test on the 405, they got approx 120W per channel into 8 Ohms, so be a bit careful, don't know your speakers, may be OK with that.

[symon]

I'm thinking of taking a rest for a bit - headache, no spare torch lightbulbs!

[spendorman]

OK, If you were nearer, I would sort it.
