For sale is this splendid example of the Ming Da Piccolo SE Pentode amplifier.
It is around 14W output, with 4 and 8 ohm taps on the very well proportioned output transformers.
As an integrated amplifier is has 3 inputs and remote volume control, via the solid all metal remote control.
It uses KT90 output valves and I have fitted some Belvu ECC82 input/driver valves, an improvement over the original Chinese 12AU7's.
Rear view:
I have fitted a direct input and internal relay to isolate the input switching and volume control, to enable use as a power amp only.
This removes the degradation from the fitted volume control and gives a very open and full bodied sound.
(Alternatively the volume control could be replaced with a quality stepped attenuator such as the Acoustic Dimension, a straight drop in).
Switch shown in direct input position:
This example has had further improvement made by the inclusion of Audyn coupling capacitors, plus a better driver stage matching.
An additional smoothing choke has been fitted to give a very quiet background, the filtering is now CLCLC.
Internal shot:
I have the original substantial double box plus packing, though collection would be preferred due to the weight.
Any trial welcome, coffee and cookies available. Willing to deliver reasonable distance for fuel costs.
Looking for £700.
