Here is my Unision Research S6 for sale.

The amplifier is about 10 years old.

I have owned it for 8 years and I inherited it from my last uncle who had it for 2 years.

The amplifier is in very good condition, as you can see from the photos. However, there is a faint scratch on the back left metal plate that goes under the power valves.

The amplifier has just been serviced by Trevor at EARS (just outside Edinburgh) - https://www.facebook.com/EARSTavira

The capacitors in the bias system have been replaced and upgraded. Everything else was tested and is still measuring within tolerance.

I would like £1200 for the amplifier. I have a set of partially used JJ KT77 valves that I could include in the sale plus a pair of Brimar 12AX7's.

The amplifier is a heavy beast, so ideally I would like the buyer to collect, or I could deliver for the cost of my petrol or we could meet up somewhere within 100 miles of Livingston, West Lothian.

The remote is included and I still have the double box plus top foam insert. The bottom one is missing, but I could try and find something to replace it with.

Bump and a reduction to £1000 before it goes on the bay of thieves and elsewhere

A photo with the valves plugged in would probably help.

The description says, "I have a set of partially used JJ KT77 valves that I could include in the sale plus a pair of Brimar 12AX7's."

Note that it says, 'could', not 'will', which suggests that there are no valves included. If it was sold with the valves, I suspect it would have gone by now.

Oh right. Well if that's the case at least it's clearer now.

I get what you are saying and I will admit that I worded it incorrectly because the valves are included.

Anyway, the amp is now sold subject to payment.
