I have a restored classic 1964 SANSUI AU-70 amplifier for sale. Reluctantly letting go because I have too many SANSUI amplifiers in my collection and need space. Specifications:

Power output: 25 watts per channel into 8Ω (stereo)
Frequency response: 10Hz to 80kHz
Total harmonic distortion: 0.95%
Input sensitivity: 0.9mV (mic), 1.1mV (MM), 50mV (line)
Signal to noise ratio: 52dB (line)
Speaker load impedance: 8Ω to 16Ω
Valve complement: 4 x 7189 [authentic Russian/Soviet era tubes], 2 x 6AN8, 3 x 12AX7.
Dimensions: 405 x 320 x 142mm
Weight: 13.7kg

These 25Watts sound like 80-100 Watts on most speakers. Have just recapped it at a specialist shop, plus replaced a few new tubes so can sell it as ‘virtually new’. Only thing I didn’t fix is the VU meter – have played it the past few years with the glow on – didn’t see the need to spend more money fixing it just to see it move. Speaker connectors upgraded to fit the latest spade and banana terminated cables. Power cable receptacle upgraded too to fit any cord with the IEC plugs! Hearing is believing! The AU70’s main characteristic sound is the silky smooth midrange and 3D soundstage, and unlike most tube amps, this one boasts a tight punchy bass at all listening levels due to the large output transformers. It can match all speakers with the sensitivity of 86 dB and higher: been tested with ProAC, AUDIOSPACE, JBL, CHARIO, FOCUS AUDIO, and PATHOS floor standers and bookshelf speakers.

This is the next most popular Sansui tube amp that is placed chronologically before the equally renowned AU111. Does very very well with jazz, classical music – the romance of warm radio sound is back again! It is exceptionally astounding with vocals. Andrea Bocelli, Nat King Cole, Diana Krall, Rosemary Clooney, Laura Fygi and Norah Jones are in your living room when you play their discs! I have mainly played CDs, digitally streamed music and radio via a standard tuner. Phono jack tested at shop – all OK.

Asking $600.00 and very negotiable.

For pictures, negotiation, demo, please text ALAN at 9-4-5-7-7-6-2-0, that’s 94577620. I look forward to your enquiries!
