This is the top of the audio line conditioning application Topaz 2500 VA Ultra Line Noise Suppressing Isolation Transformer. I have a copy of the manual, too.

Difficult to find and almost impossible in this brand new new condition.

HUGE amount of headroom and noise suppression with ultra clean power. Greater than 146 dB (attenuation) throughout the audible spectrum, up to 20kHz, equates to a 20,000,000-to-1 reduction of common-mode noise. They also provide 65 dB (1780:1) reduction of normal-mode noise.

I use an Elgar (brand, 5kVA) with the same specs where I live in a small village of 1000 at the end of the grid with incredibly dirty, inconsistent power. It’s a sonically beautiful almost magical thing to have such improved dynamics and inky black background from the ultra clean, steady and rock solid power by having the Elgar inline on a 30A dedicated line.

This Topaz Model no. 91002-31 Ultra Isolation Transformer is rated at 2500 VA, 50/60 Hz, 240/120 Volt Small footprint (approx. 8 x 8 x 15 in.) and Exclusive shielding UL and cUL listed & meets UL544 requirements Reduces common mode and normal mode noise Large opposing toroidal windings Saves valuable space. Protects sensitive loads from surges and spikes and prevents back feeding of noise from load to line Low leakage current (full safe) allows use of products in hospitals and medical labs

Input voltage 120/240 Output voltage 120/240 Common-mode noise 146dB @ 100kHz Normal-mode noise 65dB @ 100kHz Overload capacity 600% for 1 cycle 300% for 30 seconds Dielectric strength 2,500 VAC minimum Frequency 47 - 400Hz for 50/60Hz model Impedance 3 - 5% typical Efficiency 95% typical
