Thanks to all of you once again. Especially Keith ( Audiolabyrinth ), I took your advice and called Steve, the former Krell Service Manager and decided to send the unit to him for service. He is also going to change out all the capacitors and basically turn the unit back into new unless he comes across a problem with finding a certain part for it but it's gamble I am willing to take.
His website by the way is now called Krellservice.com. Obviously a very knowledgeable guy with all audio equipment and I figured I couldn't find a better person to work on my Krell.
He is not cheap...$105 per hour and let me know up front it will be apx. 4 hours of labor plus parts but my only other option was to sell the unit for parts to someone on eBay and I really rather keep it. At least as a back up unit.
Again, thank you all for your quick response.
John
