Hi, I`m experiencing tube failure on my ARC Reference CD-7 ,18 months ago I sent it back to ARC for power supply upgrade,and new tubes, the CD-7 has just returned from ARC yet again ,where it had a burned out tube that had about taken out another tube [ according to techs at ARC] ! 21 capacitors replaced ! only use this 3-4 hours a day [ piano solos at low volumes] all my gear is hooked up trough a MIT Z Series Line conditioner [ which I sent in to be serviced as well in search of the problem ! ] The tehnician there said we have 300 to 350 power downs and spikes daily here - My question is how to protect my tube gear, as I just purchased a new ARC LS-17 SE.
I had no issues ever with my solid state ARC LS-9 or any other solid state gear !
any assistance will be greatly appreciated !
