Technics SU-V4X

Hi!

Since I had a v1X and it sounds acceptable, reading the posts on the forum (many thanks to SVI2004A for the inspiration) I managed to find a v4x, but only defective. The "safety operation" led it flashes quickly and the relay does not click. I checked the supply voltages and and I have the corresponding values (+/-44v, +/-16v, +5v). I put an audio signal in it and I find it at the input of SVI2004A, all audio settings are functional.
Does anyone know if I could still find an SVI2004A somewhere?

Thank you in advance!
