speaker relay type sony TA-N77ES

powerflux · 18th May 2011, 08:41 AM

Hi,

I have a beautiful TA-N77ES, which i've been restoring over the past few months. both the output relays were bad, so i desoldered them.

The amplifier is back in perfect working order, but as you've might have guessed i've lost both relays. Can't find them anywhere. Does anyone know the exact type of the original relays?

The servicemanual isn't very helpful..

"Most" amps would use normaly open relays, so as long as you find one with a solid amp rating, it should be fine. You can measure the voltages on the switching pin traces to get the right voltage rateing.

you are absolutely right, but i want to make the amplifier as original as possible.
they are DPDT, somewhat like the omron G5R. but not exactly.

the amplifier is still working perfect by the way

the "temporary" relays i've inserted a few months ago are also failing (wrong voltage, pre-used and only SPDT so no channel B..)
but while they worked the amp sounded great with a pair of quadral shogun phonoloque gold! i *love* that amp.
had a McIntosh MC7100 for a while but the Sony beat it everytime.

i still don't know anything more then before, but a few months have passed so maybe one of you can help me out?
