Blackgate Capacitors Failure Announcement (Updated):
We have been receiving a good amount of equipment in for repair (modified by others)
over the past 3 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 the 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.
