Stunning Rotel RA-1412 Amplifier Cleaned, Serviced & for Sale!

2 Comments

I’ve just cleaned, repaired and serviced this stunning Rotel RA-1412 integrated amplifier and she’s now available for purchase.

This incredible Rotel RA-1412 integrated amplifier is now available to buy, from my friend Pierre @ Revolution Turntable. Pierre runs Revolution Turntable, one of the last proper hi-fi stores in Western Australia. It’s well worth a visit if you haven’t checked them out, get in touch with Pierre if you are interested in this beast.

In preparing this 22kg monster amplifier for sale, I had to get through a layer of dust and grime, the likes of which I’ve rarely seen. It was mostly superficial, but the differences visible in the before and after shots really are night and day.

Clean & Service

The old RA-1412 looks a little forlorn in this image…
She clearly needs some love

I’d say she’s given many hours of pleasure over the years and just needs some TLC. Handles are a nice touch.
Many ‘twiddles of the knob’ have taken place I think.
And flicks of the switches…

Let’s give her a birthday she deserves.

Knobs need a bath…

Clean knobs!
Time for the faceplate

Yuck!

Now we are talking!

And now a clean faceplate. Wow!

I know, this was really crusty before…
Just in case you forgot how crusty.
What a difference a thorough clean makes.
Time to take care of her output devices. Here, I’ve matched a set of her original output devices ready for reinstallation.
I’ve mounted them on silpads for long-term reliability.
Her beautiful meters are dead, time to repair them.
Much better, they now work, and I’ve repaired the meter illumination for good measure.

With fascia, knobs and controls back on, I think it’s time for a musical test…

Wow, just look at her, unrecognisable compared to how she presented initially.

And yes, she sounds fantastic, rich, warm and dynamic, as you would expect.

How Does She Sound?

As you would imagine, this Rotel RA-1412 sounds warm, punchy, and just fantastic. Don’t forget, you can view and potentially purchase this beast at Revolution Turntable, in Osborne Park, Western Australia.
