Amp Heads or Combos that run on 'Universal' power supply (will work overseas)

Aguilar heads have a switch in the back, at least the Tone Hammer does.
I'm pretty sure Ampeg Portaflex do was well.

 

Bergantino B-Amp

 

Mesa D-800 has a "100-120/220-240 VAC, 50/60Hz, 250W, auto-ranging power supply" according to the manual and I suspect that the D-800+ would have this feature as well.

 

Carvin BX series. I purchased a BX500 for that exact reason, well, it was extremely affordable too. Nice all around amp for the money.

 

My Tech21 VT500 will run at 110/220. Just read the literature on whatever you want/buy. I believe with some amps you also have to change the fuse as well as flipping the switch. There was thread somewhere here on the subject a while back.

 

Also shopping for an amp with the same specs as you it seems...

Traynor SB series (heads and combos) are all switchable. To do the switch, you need to move a jumper inside, procedure very well explained in their service manual.

The SB200h and SB500H heads are made in Canada and matching your requirements IMHO.

 

FTR, Markbass heads do 120/240v, but it's a somewhat involved procedure that requires a tweak on the circuit board.

 

TC Electronics RH and BH heads can be used with both 120/240v.

 

Got my Mesa D800 head in the US, works perfectly in Europe.

 

Most or all of those are auto select too. It should be noted the BX1600 and likely the 1500 are not sporting any method to run a different voltages. External transformer or Carvin can replace the internal. I'll wire my house dual voltage and use funky outlets and cords for 115. I bought an inlaw "electrician" a cordless drill and told him it was 115. Within a day he plugged it into 220 and asked me what to do. I told him it still works fine but now its a hammer. Walang laman ulo.

 

Ampeg PF800 works on any current via a switch on the back.

Carvin automatically handles 100v to 240v. I also have a Peavey VB-3 all tube amp that works the same way. Pricey amp, though.

When we had our house built here I agonized over whether to have separate 115v outlets. After six years I'm still not sure what the best choice is. I opted to just use small conversion transformers where needed. I still wound up destroying a few things even though my 115v plugs are marked with bright yellow tape. But my amps stay safe.

P.S. I replaced just about all my wallwarts with multi voltage types.

 

I can relate... Funky plugs and outlets is something I need to start buying and saving... added to the list!

Soooooooo, does a drill's battery charger work after 220V?

 

Aguilars do.

 

First of all here in the Philippines, the common outlets are standard UNGROUNDED U.S. style parallel blade outlets running 220v. So screwing up is quick and easy.

As for my antique Sears (Ryobi) 18v drill batt charger; it sounded like a .22 pistol being fired. I was able to save it, though. The electronics are protected from gross over voltage by an MOV which is what exploded. Believe it or not my buddy in the U.S.was able to get the correct replacement part at Radio Shack of all places and mail it to me. Works fine now.
