Further Information: 

I am having one last go at selling this great amp before it stays with me.

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.

 

These are very heavy, particularly the power supply therefore local pick up is preferred. 

I can however get very strong shipping boxes made so shipping is an option but you will need to organise and pay for a carrier. 

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

As I always do with amplifiers I work on, I run it through my system and I can say this is a beautiful sounding 300B SET.

A very comprehensive power supply with a rectifier tube for every tube in the amplifier section is almost unheard of.

A well looked after unit by a fussy owner.

So easy to move around now that both units are on wheels, should have done this years ago.

Just wheel into position, plug and play

This listing will expire in a couple of days and will not be relisted, instead used in rotation. 

It's a very tough market as many have expressed over this year.

If anyone reads this after the expiration, feel free to message me to discuss if I still have any interest in selling.
