Selling on behalf of a friend, a lovely Croft Vitale SC Preamplifier.
In pristine condition, this sports 2x ECC83 in the phono section and one CV4024 in the line section.

The unit has been re-capped as all the original coupling capacitors were very tired. Internal shot after re-cap:

As can be seen the Vitale is in super clean condition.
The output capacitors have been increased in value to enable pairing with a power amplifier of 25K input impedance or greater, as built it was only suitable for driving high impedance.
The phono stage circuitry has been brought up to Croft 25 level with the necessary component additions.
A Firebottle modification has been fitted that improves the linearity and raises the phono gain a little.
The phono gain is now 53dB, useful gain when the preamplifier is used together with digital line sources with large output levels.
Modified phono circuitry:

£500
Available for collection near Dudley or additional postage at cost.
