Up for sale is my Croft 25R pre-amp.
It is just 3 years old and is in excellent condition.
This amplifier has the on-board phono stage and shortly after being purchased was returned to Glenn Croft for modification. Glenn upgraded the line stage to a cathode follower circuit designed for use with the 12BH7 (or E80CC and ECC99) valves. The main benefit being slightly reduced gain and the ability for it to drive both valve and low impedance solid state power amps. The standard 25R does not work well with low impedance solid state power amps which is what I had at the time.
The pre-amp will be supplied with the original unbranded 12BH7 valve and Raytheon 85A2 regulation valve together with a Westinghouse 1958 black plate D getter 12BH7 and Mullard 85A2 regulation valve both of which have more recently been purchased and installed and which have improved performance further.
The amplifier will be supplied in its original box.
Asking £915 including insured UK delivery.
