Can someone tell me what I did wrong????

[The_Janitor]

So, are you recommending that he replace the transformer because it may fail one day?

No, he was suggesting that OP have a tech give it a once-over before using it again.

 

[JimmyM]

You likely missed the bullet...don't do that again. If it still works, the tech could do more harm taking the amps apart or benching them.

I am only familiar with the original SVT.

I think it should be pointed out for those who don't know that Mr. Hughes co-invented the SVT

Dred, I think it goes without saying that the inventor's advice is the advice you should take here. SVT transformers are all crazy overbuilt, and while they're not indestructible, they can stand up to a lot of stuff they shouldn't have to. I've talked to more than one longtime tech who's told me they never had to replace an SVT transformer.

So if it still works and sounds good, I'd take the advice of my late father, who was also an electronics whiz and used to repair flight simulators and radar equipment and stuff like that for the Navy...he didn't invent SVT's or anything but he did invent the phrase, "If it ain't broke, don't fix it." At least that's what he told me

I don't remember recommending that. The likelihood of failure is higher now but what he does about it is his call.

I have been using it 3-5 hours a day since like a week now....and its still perfect!

I think I was lucky!!

 

[Dredmahawkus]

Go to Radio Shack and buy a Basic Electronics book. (Seriously)

I understand that the amp has to be plugged in...and you cant have 2 amps plugged into 1 cab...but some reason I thought the speakons and regular plugs were seperate.....on my old set up I had a 2 cabs a 4-10 and 2-12 GK neo.....I had a messa 400 and a GK mbfusion....I had 2 speakons going out of the mbfusion into each cab....and 2 regular cables going out of the mesa tube amp into each cab......i would only have one amp plugged in at a time....and I used it like that for well over a year.
lucky I didnt blow them up!

My brain is about full up with info on other subjects......I dont have enough time left on this planet at 41 to learn about electronics now! I am using what little brain power I have left to learn music and bass!

Hope the question isn't hijacking the thread, but is there a way to accomplish what the OP wanted to do, safely?

Say a junction switch that would let you select between a couple of different amps running into a cab, taking the inactive one out of the signal path?

Technically, sure. Practically, no, if a tube amp is in the mix, as you must ensure the amp output always has a load. Unless you intend to turn it off before amp switching. In which case the whole thing is pointless.

No. Take 2 seconds, and just swap cables.

No, he said the transformer was going to fail: "It overheated and smoked. It's not terminal - yet, but the insulation is not what it was and there's a failure round the corner."

 

[Stealth Fighter]

You may not have recommended it directly, but it was implied. That is why asked if that was what you were suggesting.

One or both of those amps likely has relays on the speaker outs, or other built on protection circuits to guard against such things.

Still not a good idea though.

 

[dincz]

It sure was inferred apparently.

It's the inference makes the difference?


Ha....I crack myself up sometimes.

 

[BassmanPaul]

..I dont have enough time left on this planet at 41 to learn about electronics now! I!

At 41 Bro you're a callow youth!!! I'm 68 and I learn new stuff every day. It's good for the ol' brain box!!

No. Take 2 seconds, and just swap cables.

It could take, like 8-10 seconds, really.
More even, if you put your bass back in the case.
Totino's Pizza rolls microwave in 60.

Not that I'd eat those.

But compared to a trip to the tech to fix your fried amp?....

 

[Chef]

Mmmmm.....fried amp.

Yeah. One cable at a time.

It's less about saving time than it is the inconvenience of getting around to the back of the heads in the tight space of my studio. There's plenty of room for the amps to breath. However getting behind them means moving a few things. Not a big deal but it would be a convenient to be able to switch them if there is a way to do it safely. I can remember to power down an amp before I switch.

Cool, thanks. Serious question for the pizza eaters: Can you see any reason why this solution would be a bad idea?

 

[The_Janitor]

Radial covered all the bases on those switchers, there's dummy loads that take the place of the speakers when they're not switched on.
