H.H. Scott Type 130 Stereomaster Stereo Valve Pre-Amplifier – For Repair / Restoration

Vintage H.H. Scott Type 130 Stereomaster stereo valve preamplifier, dating from approximately the late 1950s / early 1960s.

Serial No. 06929.

This unit is being sold strictly as non-working and for repair/restoration.

The last time I used the preamplifier, I noticed a burning smell, after which the audio output stopped and the unit ceased working correctly. I stopped using it and have not attempted to power it up again since.

Because of this fault, I strongly recommend this unit only to an experienced vintage audio technician, electronics engineer, restorer, or buyer who is confident working on high-voltage valve equipment.

I would not recommend this unit to someone looking for a ready-to-use amplifier, or to anyone without the appropriate technical knowledge to inspect and repair vintage valve electronics.

Cosmetically, the unit remains in good condition for its age. The front panel, controls and lettering are generally well preserved, and the wooden cabinet is complete, with normal age-related marks, scratches and some wear to the edges as shown in the photographs.

Internally, the unit has clearly received servicing and component replacement during its lifetime. Various capacitors and other components have been changed, and the rear RCA sockets also appear to have been replaced/upgraded. I do not have documentation detailing the previous repair work.

Please study all of the photographs carefully, particularly the internal photographs, as they form an important part of the description.

Important electrical information:
The unit is marked 117V / 60Hz and is a US-market model. It must not be connected directly to UK 230V mains.

Given the fault described above, I would strongly advise against powering the unit on before it has been inspected by a suitably qualified technician.

Supplied exactly as photographed, including the wooden cabinet and the valves currently fitted.

Sold as seen, non-working, for repair/restoration. No guarantee is given as to which components require replacement or the extent of the repair required.

This could make a worthwhile restoration project for someone familiar with classic H.H. Scott valve equipment.
