Default can a sony ta-n611 be bridged?

I have 2 old sony TA-N611 150 wpc amps.
Can I one amp to drive the right front speaker
and use the other to drive the left front speaker?
Can these amps be bridged?
How much power will they make bridged?
How would I hook it up?

Thanks in advance,

detect the feedback resistor of the main amp . ground the input of iverted amp . double whit the same value this resistor and joint to the feedback inputs .just you need its 1 resistor .

The amp's PCB tracks in the output stage would have to be able to carry at least double the current..

Hi vibeline,
Don't do this. Consumer grade amplifiers do not have the heatsinking, output stage or power supply to survive this. If you insist in destoying your equipment, you can buy bridging adapters. Do not start messing around inside your amp.

Other things to remember. An 8 R load looks like a 4 R load to a bridged amp. Output power may only double, a +3 dB difference that is hard to hear. Bridged amplifiers normally do not sound as good as the same amplifier running not bridged.

So, it's up to you.

-Chris

True.

Far better to design a bridged amp. from scratch, or one that is specifically designed to operate in this mode.

Hi claudiomas,
When I ran my audio service shop, I repaired more damage due to what you are recommending vibeline do.

So go feed the service guys, times are tough for them! But don't take anyone else down with you.

I am glad your gear hasn't blown up yet. Buy a lottery ticket!

-Chris
