Up for sale is my Croft 25R pre-amp.
It is just 3 years old and is in excellent condition.
This pre-amplifier was returned to Glenn Croft for modification soon after being purchased. Glenn upgraded the line stage to a cathode follower circuit designed for use with the 12BH7 (or E80CC and ECC99) valve. The main benefit being to reduce the excessive gain of the standard version and to better enable 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 originally had at the time. As I understand things Glenn also prefers the 12BH7 valve which he also uses in the 25RS version.
The 25R incorporates a superb onboard phono stage which I understand is a slightly improved version of the standard RIAA phono stage which is available as a free standing separate component retailing at £500. The onboard phono stage avoids the need for a separate box, use of a powered socket and potentially expensive interconnects.
The pre-amp will be supplied with the original unbranded 12BH7 valve originally fitted by Glenn and the normal 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 pre-amplifier will be supplied in its original box.
Asking £875 including insured UK delivery or £850 collected from sunny Ipswich.
Any questions please ask.
