I have certain things that I search every day. US AMPS is one.


Did you not get any buyer? if I had the money I would have jumped all over that one

 

[paulc35]

I hated that i needed to sell it and listed it at $420 some watchers no sell. Then stupid on my part dropped it to $300 and stated i would end the sale at midnight. Either the people watching it didnt have the cash or didnt know what was in front of them. I had already given a Zed built Class A amp away for $75 so I thought if someone buys my tu4360 at this price I'd hate myself so I ended the sale about 3 hrs early. Glad i pulled it.

honestly had I known it was going to get pulled sooner I would have tried harder to get it. I was actually looking at some US AMps tubers lately.

saving searches or searching manually? I have a few searches saved myself, and then auto bidding software to win the auction. saved shidload of money over the years.

Sell your Butler, and buy one TU-4360. The TU-4360 is a much better amp. Own both and the Butler was just gutless and tinny sounding.
There's also a few threads that "apparently" demonstrate how the Butler can still play music if you pull the tubes out...

find me one, would you?
As of finny sound.. yours probably was defective as mine bottoming out 100w 8 Ohm speakers with ease, I wouldn`t call it gutless nor tinny

While doing some looking around I thought I read as part of their advertising that us amps stated their tube amps will not run without the tubes unlike some "fake" tube amps.

I saw a thread on here mentioning it also.

he was talking about butler running without tubes, not us amps, i searched for that found nothing but rave reviews of butlers.
I guess i`d pull tubes put tonight and test it myself, I highly doubt it will work without tubes, given how it takes 10 seconds to activate tubes warming up circuit and no sound coming out of it until then.

That is what I said. The butler amps will run without the tubes.

And the us amps literature stated that compared to other tube amps , theirs will not run without tubes.


And like I said. If you search google for us amps tube amps you will find at least a thread that mentions the butler amps running without tubes.

I didn't have time to locate the source of the claim but go ahead and pull your tubes out and see.

I will ask my tech. He knows.

 

[Victor_inox]

OK cool

 

[Victor_inox]

butler audio located in 30 minutes drive from my house in Aurora,CO, I should probably just call them and ask, I `m not looking forward of unscrewing 14 screws to take tubes out.

Took me 15mns but you're ready?

^ this is just on DIYMA - too lazy to search on other forums but when I first heard about the tube romoval thing, that was on caraudio forum I think... When I had the Butler, I wasn't on any forum yet. It's only after I sold it that I saw those kind of threads...
When I said gutless, I did not mean it does not put out rated power - but compared to the US Amps, it did not have as much headroom and the difference is not subtle even though both are rated for about the same power... Bottoming out a speaker doesn't say anything about power or guts

* US Amps not working if tubes removed:

This is reply by the designer of the thing, IMO he has much more credibility that guy in first link you posted,he designed one of my favorite guitar pedals and he has tremendous respect in guitar players world. BTW I can find rave reviews of said amp on this very board.
A rumor spread by some ill-spirited and jealous PPI engineers perhaps. The amp has a fail safe circuit which will allow it to operate in solid state mode if the tubes fail. This adds to the confusion. Why would I risk 25 yrs reputation with pro musicians, etc and not have the tubes operational?? Makes no sense.

BK Butler

so if you read some more you`ll see that rubes works in diode mode, therefore can be disconnected without significant change in sound. that what I read, I havent pulled tubes out of mine- according to butlet it`s pointless because solid state circuit will be hot anyway. Is US amp better- maybe, maybe not, it`s a matter of opinion and I`ve heard yours. we hacked that topic to the end we should stop, really. OP I apologies.
