Lifetime of Auricap capacitors ?


Does anyone know the approximate lifetime of these capacitors ?
I have not been able to find this information and the derating curves with temperature anywhere.

Please do NOT respond if you believe fuses or cable lifters or cable burn in makes a difference to the sound.

Thanks

Quality plastic caps will outlast us both cakyol so long as they're not used too close to their max voltage, up to 70% is still fine

But those things in the power supply side
do NOT.

Your system may not be resolving enough or your hearing can't or won't hear them.
Try this. It won't cost you anything. Warm up your gear. Listen to a good recording. Power down. Wrap a few turns of masking tape around the glass part of the power fuse in your preamp taking care not to touch the steel caps. Listen again.

Voltage and temperature may affect their useful life but that's nowhere near electrolytics. With -55 to +85 degrees they could last more of a life time unless you place them exactly next to a tube.
