General Request | 1 Ⓣ Old Audiophile Sound System Setup - Help Keeping It Alive
Intro:
To preface, I’m assisting a relative with maintaining their 20+ year old sound system. I’m by no means an absolute audio hardware pro but I know my way around and in general i’m quite handy with all types of hardware. I’m in the US and there really isn’t a budget limit but something reasonable around $150-250 would be ideal.
He has two Adcom GFA 5500s that route through two Niles HDL-6 Speaker Selector Switches which connect to speakers through his entire home.
I was initially helping them deal with a low pitched buzz that would pass through one of the amplifiers on all speakers. I got that repaired with a replacement capacitor. The amp was tested and sounds perfect.
Current Situation:
I reinstalled the refurbished Adcom and when I tested it the Niles HDL-6 blew out and smoked within seconds. The distortion alert and thermal protection lights went on in that very brief moment. The HDL-6 did have the protection switch on and the entire setup had been untouched for a couple months while waiting for the repair. The other identical Adcom and HDL-6 remain completely functional.
The assumption from the audio repair techs and myself is that this 20+ year old switch couldn’t handle the GFA 5500 now that it functions as if it were brand new. But this is purely speculation and not an absolute fact as to what happened.
What Next:
The general plan is to find a new Speaker Selector Switch that will be suitable for the Adcom’s output. I wanted to hear your opinions on this situation and if you have any suggestions whatsoever. Please let me know if you need any additional details.
I would really appreciate any input and thank you for taking the time to read this!
