Silvercore 833c Monoblocks

[AD Audio]

https://i.imgur.com/dPlplc6.jpg
For sale a pair of these amazing monoblocks. These amps will appeal to those who love aesthetics as much as good sound. Your dinner parties will enjoy the conversation piece of 20 watts of single ended magic and the Van de Graaf looks. 833 transmitter valves provide the output driven by a pair of EL34s and a silver-wired input transformer. Attenuation by a front panel knob means these can be used as integrated amps. The amps operate silently and coolly. The output tube is capable of 1800 watts but is tuned to deliver 20 watts and is cooled by a whisper fan. These amps will drive virtually any speakers as the review below indicates (where the reviewer was using tannoys). Any demo possible. Pick up only as these came in plastic crates so do have boxes. I will also travel up to 100 miles for a swap etc.

£6,500

Is this a Tom's amp?

Is this a Tom's amp?

These were owned by Tom. We swapped my Leben, which he'd previously owned too, for these, as he felt the Leben had more bottom end grunt than these with his difficult to drive Tannoys

[AD Audio]

I've had a few messages asking why I'm selling these........In our household we have three pairs of monoblocks-my wife's Mastersound 845s, my own build Radford sta100 monoblocks, and these, not to mention a Radford sta 100 stereo, and a Radford sta 15. One household simply cannot use so many amps. There's little between the three pairs of monoblocks in terms of sound quality: of course they are different and have differing drive capabilities and output power but there is no better or worse. I can't sell the Mastersounds and I built the Radford sta100 as my statement amps, so want to hang on to those.

[AD Audio]

And to cut off a few more questions, these amps are autobias, so no adjustments are necessary. The life of the 833 tube is described as more or less indefinite at the rated power output and the EL34 driver valves should last 5 years or so, or longer, as they are run at a much lower dissipation than when used as output valves.

These are fantastic monos. I have heard them at Tom's and that was one of two times I have liked Tannoys - I thought they were quite superior to his Radford 25 and Radford 100 in Tom's. I have also heard these on Pnoe (AER BD4) with compares to Thomas Mayer 45/2a3. I have heard them on Devore Orangtuan O 96 and compared them to various amps including Jadis integrated 100w, and have compared them to Thoress on hORNs Universum. Also heard them on Silvercore's own horns. I am a fan.

I strongly suggest evaluating them with his stock lower priced Chinese EL34 before you try others. I have compared those to Telefunken dual getter in these amps and he had voiced it musically to his Chinese tubes.

Certainly can’t be a cooler looking set of mono’s, sadly out of my price range, but one can always dream!!

It says something about how good they look that I'm considering keeping my leaky asbestos garage for a few more years to get them [emoji38]

Ah but my whole garage is asbestos and it's on a 6' brick raised platform, replacement cost about £10k!

Hi David

I see lots has changed since I collected my AI 500 , How do you rate your new speakers , Are they JBL's

[WESTLOWER]

Exceptional amps

Hi David

Hi Al,
I now have JBL K2 9800 speakers which I love. They work better than the Tannoys in my lounge, as they work better up nearer the wall, and also the drivers are at a better height when seated on the sofa compared to the Tannoys. I do have an excess of power amps at the moment having these 833s, my Radford sta100s built as monoblocks, a Radford sta100, my wife's Mastersound 845 monoblocks and some Ming Da 805 monoblocks so something has to go! Ironically, the Silvercore's are probably the best at driving my JBLs but my wife's Mastersounds have to stay in the lounge, so there's no choice there! I still normally have a couple of AI500s in the workshop too!

[bumpy]

The chances of auditioning these is zero, so would someone like to compare them against some of the best SETs - say a 300B. (Given the slight power difference)

[AD Audio]

Having had amps based on most valves including 300bs I would say:
-much more drive and output than 300b SEs with the ability to drive even difficult loads like Tannoy speakers as Tom (Montesquieu) used them for
-more even handed across the frequency range than 300bs, with powerful bass and extended treble
-better treble extension than 845s
-detailing /musicality as good as 2A3s /6B4Gs

Hope that helps!

Does this mean it has the beautiful euphonic midband of the SET.

Absolutely! They have that SET magic in abundance, no push pull edginess here. Now under offer so if there's any lurking interest here, now's your chance! Make an offer and I'll throw in delivery to any UK address

At last!:)

[AD Audio]

It did take a while. It's a lot of amp for the money, and engineered to last for ever but the brand name is fairly unknown over here. Decent output for an SE amp and will drive anything too. But given the lockdown scenario, it's perhaps not too surprising they took a while. Gone to a good audio home as well so that's great!:):)

:):D:cool:

[Filterlab]

Beautiful amps. I hope the buyer thoroughly enjoys them. :)
