Hi Keith,
Thanks for testing it—I have a meeting with the shop booked for later today and will bring this up. There have been no design changes to the PS-100 for a while, so I expect it to be a tube failure. But I agree, it would be good to completely understand this double failure. I’m really sorry about this; we will figure out what went wrong, let you know, and make it right as soon as we possibly can.
Can you tell me the serial number of your PS-100(s)?
What do you want to do? I think these are the options:
- Replace tubes and fuses yourself (we will ship them to you for free)
- Contact Zzsounds for another unit?
I’ll write again after I have spoken with the shop.
Regards,
Dan
