Audion Mk1 300B PCB

Silver Night Stereo or Stereo Integrated Printed Circuit Board Power Amplifier

5 Star Awarded
5/5

Audion Silver Night Mk1  PCB 300B stereo power amplifier and
integrated stereo power amplifier.

Audion Silver Night Mk1 300B PCB stereo is our entry level amplifer in the intermediate range, using the well known 300B tubes. This amplifier is hand built on a quality substrate pcb (printed circuit board). The triode based Silver Night stereo amp uses no (zero) feedback in the design. The chassis is black powder coated aluminum as is the transformer cover. The top plate and badge are mirror finished stainless steel.

The Silver Night range represents our intermediate level range, still affordable and using quality British, European or American components. The entire range of Silver Nights all reproduce truly and faithfully fast transients and beautifully musicality. Like all of our amps, no bloated bass or “tinny top end” Just perfect reproduction of finite detail that bring a total listening experience, and work with a wide range of loudspeakers that truly exhibit all of the subtleties, details and nuances that valves with a zero feedback design give. 
 “Yes – its a great amp” – Constantine Soo

The Silver Night MK1 300B triode based amplifiers uses unique circuits and of course our own output transformers. See the tabs below for list of options to suit your needs

Audion Silver Night DUO 300B/2A3

Audion Silver Night Mk1 300B PCB stereo

The Audion Silver Night Mk1 printed circuit board 300B stereo amplifier or 5 channel integrated stereo power amplifier which has a  passive pre-amplifier built in so you can use up to 5 line level inputs. The integrated amps even have an un-attenuated output for feeding directly to a tape recorder or active sub-woofer or even to another amp for bi-amping.

All of our single ended amplifier designs use unique circuits and are auto-biased so don’t need regular bias changing or complicated setting up. They are virtually “Plug and play”

The Mk1 Silver Night is ideally suited to loudspeakers of 89db or greater efficiency. Having a volume control on the front often negates the need for a separate pre-amplifier. The amp deliver 7 watts into 8 ohm per channel. We use JJ 300B and Russian New old stock 6H23N as an input  and NOS Jan Philips 5687 driver tubes.

Sonically, The JJ300B Triode valves used in the Silver Nights give subtle nuances and texture to the music allowing  a good level of musical data retrieval. The 300B is a very well known valve that can reproduce delicacies and yet be punchy at the same time.

The chassis is made of military grade aluminium, with a durable black powder coated finish. The top plate and badge are finished with mirror polished stainless steel.

Product options for both type of stereo or stereo integrated power amplifier.

Upgrades available for the printed circuit board versions include changing Signal Capacitors, wiring audio path in solid silver, WBT Binding posts and RCA’s etc.. Speak to your dealer when ordering your amplifier. Any further upgrades and we would recommend going to the hard wired Anniversary versions  

There are options for both versions of the MK1 amplifiers to upgrade to solid silver wound secondaries or primaries and secondaries on the output transformer. However we would recommend going to Hard wired Anniversary versions before changing output transformers.

We also offer a remote volume control for both stereo and stereo integrated power amplifiers. New for 2020, full remote control option with built in 63 way stepped attenuator, remote channel change and volume as well as power off. Full metal handset.

Upgrade options and upgraded product categories direct from the factory.

We offer 2 upgrade classes for the Silver Night MK1 PCB, however we strongly advise moving to Anniversary or Special Edition versions for these upgrades,.. The upgrade classes are 
Insignia Class which uses a full silver wired audio path, better graded components again in the audio path, tantalum resistors in the critical places and WBT binding posts.
Excelsior Class uses the same as above but with the inclusion of Teflon/Tin foil V-caps, Internal Solid Silver wired Interconnect, a 43 way Stepped attenuator, better power supply capacitors and WBT RCA’s. 

There are options on both classes for solid silver wound secondaries or primaries and secondaries on the output transformer.

The Silver Night is a detail retrieval machine which benefits almost every aspect of performance, from dynamics to dimensionality. All recordings I listened to had a layer of haze removed. Whether from the simple circuit, or point-to-point wiring, or high quality parts, or all triode tubes, the Silver Night might be the most transparent amp I’ve used.

Heard this Silver Night Mk1 PCB 300B alongside the Cary CAD300SEI and it blew the Cary out of the water. Much cheaper, but fuller sound; full 300B triode wonders flows from the Audion

The sound was a contrast, detailed and extremely musical. There was no slowness and desire to lull the listener, for which I dislike for a directly heated triode single end.

The Audion Silver Night Mk1 is all music and beauty—rich and warm, with an ever so slightly euphonic midrange. The Audion allows the listener to relax and be enveloped with their choice of musical drug. It will not reveal every last detail hidden deep in your discs, but that’s okay if you’d rather listen to music than to the bits and pieces. Sure, with the pcb version you give up a touch of clarity and transparency, along with some treble energy, and no, the Audion will never really plum the depths of the bass region with the tightness, speed, and clarity of our Clayton M70s, but let me tell you, the Audion never failed to amaze me with what it could do musically or sonically
