AI-assisted summary

Description from the seller

Vintage stereo amplifier that was produced in the early 1970s.

The delta 70 is technically nearly identical to its well-known predecessor, the Leak Stereo 70.

Design: wood case with an aluminum front panel.

Sound: very beautiful, warm and musical.

Specifications
Power output: 35 watts per channel into 8Ω (stereo)
Frequency response: 30 Hz to 20 kHz
Signal to noise ratio: 56 dB (MM), 66 dB (line)
Speaker load impedance: 4 Ω to 15 Ω

Modification:
Replacement wood case.
Terminal made suitable for banana plug.
Plastic knobs replaced with aluminum knobs (old ones were prone to breaking).
RCA plugs sit very close to each other; a known issue with the Leak 30 and 70—use older, thinner cables, or on new ones cut a small strip of the plastic away.

Photos are of this lot.
