Blackgate Capacitors Failure Announcement (Updated):
We have been receiving a good amount of equipment in for repair (modified by others)
over the past 5 years  that has become suddenly defective for the customer (output
channels failing, no sound, power supply failures, disc reading issues, etc). We have
been discovering internally shorted out blackgate capacitors installed previously that
are prematurely failing or failing due to heat, etc. Blackgate capacitors have a 85 degree
temperature rating celcius (which is 20 degree below normal high performance marketed
caps... ) and in tube gear or similar that generate heat in the local area could lessen the
life of locally installed blackgates. Heat is the largest culprit of component failure.  The
Rubycons/Panasonics replacements are all rated at 105 degrees Celcius and have much
longer longevity, have lower internal impedance and sound better for longer time
period, cleaner and clearer, better speed. Heat, humidity and moisture shorten shelf life.
If you have any equipment modified with blackgates, please keep this in mind.  
If your interested in finding out more information, please
email us here.
