  1. Amanero USB receiver, TPA Buffalo DAC, Mercury I/V stage. Plus a tube output buffer?
  2. These are only rated for 300V so need to be mindful where they are used.
  3. Happy Birthday Chris
  4. @JoaMat: I see you have been using Mundorf Silver/Gold/Oil capacitors in the coupling positions of your Megatron. These caps are rated at 600vac/1000VDC and being an oil-impregnated caps they are susceptible to high temperature (factory rating is up to 85C/185F). Also, the Megatron PCB shows the coupling caps between 12au7 and 12ax7 rated at 600v and 1000v for the caps between the 12ax7 and EL34. Have you experienced any issues with using these Mundorf caps in Megatron over time?
  5. Did you see the for sale section where there is a used BHSE offered for sale in England?
  6. I don't know what Martin thinks but Michael thinks freestanding on the PCB will be fine 😉
  7. Hook up this little gem today with the SR009 after a long break and just let the music flow...
  8. Kevin can confirm but I am pretty sure you'll be fine - the current draw is very minimal like a few 10mA IIRC. Unless you are dropping some unusually high voltage through the GRLV there is not much heat to dissipate for the MJW21193/21194.
  9. It certainly got the family look. Maybe someone at Dyson got creative with spare parts from their vacuum cleaners.
  10. Hmm, that is odd. Sorry, did not read carefully that only one of the two channels behaves abnormally. Did you check if both channels have the same output bias?
  11. This "Normal" behavior has been my experience as well but I also found the magnitude of offset drift is closely related to the case temperature of the output device too. Does the heatsinks of your Carbon get significantly warmer when the amp warms up? I am theorizing that if the amp has oversized heatsink that barely gets warm the offset may drift much less. But this is just a guess.
  12. That looks like a Grounded Grid?
  13. Happy Birthday Nate!
  14. Happy Birthday Craig!
