EXPIRED AUDIO SYNERGY 300B SET POWER AMP WITH EXT POWER SUPPLY

[Mendes]

Further Information: 

There are 300B SET amps and then there are 300B SET amps.

For those that know Cliff from Audio Synergy this is one of his final evolution of SET amps.

It is a two box design. One purely for the power supply and one dedicated to signal, they are joined by umbilical cables at the rear.

The signal side has a pair of 12AU7 signal tubes feeding a pair of 6L6 driver tubes before a pair of 300B output tubes. 

The Power supply consists of two power transformers. The smaller is dedicated to the two 12AU7 signal tubes with the larger more robust handling the 6L6 pair and the 300B pair.

Additionally each tube on the signal side gets its individual rectifier tube and choke.

There is a lot of copper in the power supply.

A pair of 6X4 for the 12AU7 pair.

A pair of 5U4GB for the 6L6 pair.

And finally the 5R4WGA pair for the 300B pair.

 

What this combination gives you is a scale, dynamics and control over speakers rarely achieved using 300B tube designs.

You will get 8 watts of SET goodness!!

It will come with the tubes shown in situ and spare tubes for everything, which will consist of -

• 1 pair Tronal 300B
• 3 pairs 6L6 as per pics
• 1 pair Hewlett Packard NEC 12AU7
• 2 Pairs 6X4 as per pics
• 1 pair RCA 5U4GB
• 1 pair 5R4WGA

 

I recently purchased a First Watt F8 with the intention of swapping the two amps in and out with my DeVore O96 Orangutan speakers.

The reality is that is not happening, so am offering this beauty up for sale for someone to enjoy.

If it does not sell at asking price I will happily keep it as it is wonderful.

If you have the right speaker efficiency and impedance these are for you.

 

I do not have any shipping boxes and these are very heavy, particularly the power supply therefore local pick up is preferred 

but I can deliver to a local Pack & Send of your choosing, subject to-

All reasonable care from my end , but responsibility and arranging/ liaising with P & S  is for you.

Very happy to audition for you with my Orangutans.

More pictures are available and happy to answer any questions via message.

 

Since the previous listing, I have had the amp checked out and given a clean bill of health by our own @Ihearmusic , so the new owner can buy with confidence.

 

Thanks for looking

This must sound like heaven,

beats down commercial brands many times of the asking price

Someone in the West will be very happy. It must be difficult selling this amp.

Happy deliver to pack and send  , but yeah , I understand, it's a long way to transport.

I do now have access to very good shipping custom boxes, see my other FS listing.

I can't take that risk shipping it to Sydney  especially with tubes. I have a smaller 300B amp and I absolutely love it and would love to have this.

Understand, tubes would all be removed and sent separate to amp in padded boxes with the spares. But like I said, I get it 

I am listening to it now playing some jazz and wondering what the ##ck am I doing selling it 

 

Oh well.....the FW F8 is great also 

[Mendes]

If anyone in Perth is on the fence, mildly interest or just curious what these sound like with the Orangutans?

 

I am happy to demo tomorrow Sunday 20/8 between 11-00 am and 2-30 pm.

 

PM for details, @Pops110 and @cafe67 a good chance to listen to the Orangutans with some jazz.

 

Cheers

Ooof, so so tempting. Gotta wait till November though. If it's still around then I'll be calling over. Love your gear!

Another time Dave.

I up was in Perth on some audio stuff and really wanted to hear Steve's 300B amp as I have an interest in a 300B amp. I have heard some very good stuff over the decades and own a bit too-tubes and single ended amps, preamps etc. There is a lot to like about this particular 300B amp. It is a very worthy contender and for the asking price, with all spare tubes is a cracking good deal. A seriously, undeniable really good deal, a no brainer in fact. 

 

The chassis's are big, robust and appear to be very well made. The amps sounds very special. It is hugely dynamic, and I mean hugely! It has incredible drive, and a real snap with richness of tone and body to it without sounding thick and syrupy. Jazz and vocals particularly sound pretty damn good with a very engaging sound. In fact it doesnt sound like your typical 300B amplifier, if thats what you are used to. In that regard though, my experiences are that the better/best 300B amps dont sound like typical older 300B amplifiers. They sound much better and this is one of those. It has great extension at both ends of the frequency ranges and the bass is defined and tight. Pair it with a very good tube preamp and it will dleiver. A great deal for somebody for sure. I hope it stays in the west so we can hear it again some time.

@AuDrewim not sure if your speakers are efficient enough, but if they are ……

Edited August 20, 2023 by PKay

[AuDrew]

I’m sure they would be just fine…

8 watts of 300b SET ain’t the same as 8W of solid state!

[Mendes]

If anyone outside of WA is interested.

 

I now have access to some very robust custom made shipping boxes (you can actually stand on them they are that strong, thank you  @rockeater).

They can make me a double box arrangement for each module and the pricing is very good.

The tubes can be removed and packed safely and separately.

You will still need to arrange your own shipping but I can now pack very safely.

 

Send me a message and we can chat about the logistics.

 

I have been listening to the amp again over the last 3 weeks and if it does not sell soon, I am very likely to hang on to it.

 

It would be good to see it go to someone who can enjoy it.

And I happen to have a set for speakers.

Can supply dimensions if anyone is interested. Mid size floor standers size.

Now on wheels for easy storage as the listing runs out at the end of this week.

I got tired of lifting that power supply module.
