Sunfire Signature 600 is working again! Yea!

Some of you might know this, two weeks ago I was listening to my system with my beloved Sunfire Signature 600 pounding away into my ALIII's and all of a sudden it shut down and went into protection mode.

I went over to see what was wrong and the case was so hot I could not touch it. I said to my self, Oh $hit! I blew up my amp. I swapped it out with a Sunfire 300 and let it cool down.

I was able the next weekend to do some investigating to see what is going on. I first had it on with no load and no speakers hooked up to it. I left it on for over an hour and the temp of the unit was were it should be. I then hooked it back into my system and started to play some music though it at low volume. It seemed to be ok after 10 minutes so I up'd the volume to about half my normal listening level and after about 1/2 hour I went over to see if it was running hot or not and well it was getting pretty hot.

So here comes the good news in this story. I talked to my good friend Tom, beemers417 at Vintage HIFI, and he said bring it down to the shop and he and his new tech will take a look at it. So last night I put it in the back of my car and went down to the shop. In about 2 hours Anders, Tom's new tech, emerged from the back room with the amp and proceeded to hook it up to one of the demo systems in the shop.

Anders fixed it. He replaced a couple of resisters and something else, can't quite remember because I had a few beers in me, but we started to put the amp through it's paces and it was running cool again.

Thank you Anders and Tom for fixing my amp.
Some cool Carver stuff!

Yeah, right. *rolls eyes*

I don't believe you.




















You had more than a couple of beers. :D

I said a few beers.
A couple of beers = 2 to 4
A few beers = 4 to 8
Quite a few = 8 to 12

I am brining the 600 down to CF. We can hook it up to your SDA's and see.

Mine is sitting on the deck with me playing Ella as we wait for rain - [-o< [-o< [-o< [-o<

I have to say this amp is a bargain.
It is good to know it can be refreshed if it ever needs that.

It is fun that a guy like Tom has a spare to stick in better than most own -- =D>

How many here have good amps not hooked up for a while for emergency? :lol:

I have a 5 channel 505 and a 5 channel 705 going to waste. Biamped, both are excellent stereo amps.
What do you have in cob webs?

I thought you said after having "Quite a few Beers" You could not discern from the 2 to 4 or the 4 to 8 or the 8 to 12 theory so you just stuck with the (A few beers = 4 to 8 ) cause you were drunk driving with a truck full of amps and after Quite a few beers it only seemed like just a few... #-o

Not a Carver amp....but it was a killer amp in it's day. Home grown- based upon a circuit designed by Marshal Leach of LSR&D. Built 3 of them, pre-amp and active crossover w/speakers

I do not have a gallery here.....so this will disappear in 30 days-

HUDSON, Florida (AP) -- A man told Pasco County Sheriff's deputies he had about 10 beers too many as he celebrated his birthday.

Fifty-eight-year-old James Taylor says he drank 48 beers on Thursday evening, prompting a stern lecture from a deputy for causing a disturbance at Hudson Beach.


If he had stopped at 38 - no problem -- ](*,)

Actually, The beer we drink is 2x to 3x stronger than regular swill. 5x over Ice House.

I don't wish I lived there, but I wish yall lived here.

As a side note, I have a few precious bottles of a very high alcohol stout I carried to the next level using Champagne yeast after the other yeast expired. Only a few can appreciate this, and you seem to be one. They are left from a batch made in 1999 and about at peak right now.
Help me with my Bob Carver amp and I will share.
