As I have a big itch to scratch, and am being nagged by the Mrs to simplify my HiFi, I am looking at swapping out my preamplifier package. Before I split it out I thought I would see if there is any interest in this as a complete package.
I have attached a few pictures of the kit (in-situ) to abide by the rules, but will get better pictures later if any interest is shown (after I have dusted the boxes ready for flash photography).
Pro-Ject Pre Box RS - RRP £749 purchased in Nov 2014

Audiophonics Linear PSU - RRP €200 (approx. £150) purchased in Dec 2104 -
(Being totally honest there is a slight problem with the voltage display panel having dead sectors, but does it not affect performance. It's only €5 for a new one. I just don't see the need to change it.)

Various valves (majority bought as "matched pairs").

Now the manufacturers blurb:
Pre Box RS
• Fully balanced double mono design
• Ultra-linear and ultra low noise
• Pure Class A circuitry
• Input switching via relays
• Low ESR capacitors
• Blue Alps volume control
• 3 XLR & 3 RCA inputs
• 1 Pre–out XLR & 1 Record-out RCA
• DC power supply (< 1 watt standby power)
• IR remote control included
• Metal casing protects against vibration and interference
• Available in silver
Technical data:
Tube assenbly 2x ECC88 (6922 )
Frequency response 20Hz - 50kHz (+ 0/- 0,08 dB)
Signal to noise ratio -95dB (IEC -A)
THD 0,06%
Line-level inputs 3 pairs XLR & 3 pairs RCA/phono sockets
Input impedance 150kohms
Gain 18dB (XLR)
Outputs 1 Pre-Out (XLR), 1x Rec-Out (RCA)
Outboard power supply 18V/1A DC
suitable for your country's mains supply
Power consumption typical 700mA / < 1 watt standby
Dimensions W x H x D 206 x 72 x 200mm (210 with sockets)
Weight 1950g without power supply
Ultimate high-end sound with 3 XLR & 3 RCA line inputs!
Four specific characteristics make this a true high-end preamplifier: 1. Fully balanced double mono design 2.class-A circuitry with no negative feedback 3. Tube output stage 4. Separate power supply as an upgrade option for further improved sound quality.
Pre Box RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with flexibility to use XLR and RCA sources. Perfectly combined with Pro-Ject Amp Box RS amplifiers, Pre Box RS will give pure sound experience, that the real audiophile is looking for. Pre Box RS utilises a luxury casing, that is available in silver or black finish.
Audiophonics Linear Power Supply Currently set to 20 volts
Description
Evolution of our previous supply, it is back with a digital display in a smaller package using the new PSU S2 module.
This new linear discrete stabilized 15V power supply is ideal for any audio device that requires this voltage, V-DAC, TA2020, etc.
This power supply uses a linear actuator capable of delivering 4-24 VDC (we can configure it to suit your needs to the voltage of your choice on request in comment field).
Characteristics :
• housing with 3mm aluminum fascia in Black
• Start-up via ON / OFF illuminated by a blue halo
• Outputs on sockets Jack DC 1.3 and 2.5
• Transformer 30 VA - 2 x 15V
• 4 diodes BYR29 F on radiator
• 6 PANASONIC CF Capacitors 1200uF / 63V Low ESR (105 °)
• Voltage Regulator LINEAR TECHNOLOGY LT1083 5A
• 2 PANASONIC CF Capacitors 330uF / 35V
• 6 Capacitors MKP
• Integrated discharge resistor
• internally adjustable output voltage
• Output + V rectified voltage
• Blue Voltage Display
• Dimensions: 185 x 185 x 50 mm
• Weight: 1.7 kg

Various 6922 compatible valves for the Preamp:
I currently have 1977 Vintage Russian "REFLEKTOR" Tubes 6N23P-EV (E88CC/ECC88/6DJ8 equivalents) fitted, and if selling as a complete package, I will leave these in. If not, I will put the standard Electro Harmonix 6922EH valves back in.
Other valves include:
2x MATCHED 1970's E88CC TUNGSRAM
2 x 6N23P = E88CC = ECC88 = 6DJ8 Pair Voskhod Rocket NOS valves
2 x 6922EH Electro Harmonix valves
2 x Tesla ECC88 "32" code valves.
Total cost of the additional valves alone was in excess of £150.
So, a total pre-amp package with enough valves for a bit of tube rolling - if you fancy it or plentiful spares.
I would like £550 posted (to the UK or EU) for it as a complete package.
I'll post up some better pictures if there is any interest.
