Hi, I live in Chile and purchased a mini jubilee head from USA. The amp is configured for 110 volts and the domestic voltage here is 220 volts. I’m going to buy an external transformer. What is the optimal wattage rating I should be using for this amp?

Thanks in advance,

Carlos

Hey 

I noticed this a few days ago. When i plug in my 2525H head and run the overdrive channel, there is a very strong loud (sounds like) electrical noise. It goes away when i remove the pedals hooked up into the loop. 

Now i run a couple of EQ's, mxr 10band eqs on 18v power and a DD7 delay pedal in the loop. I have checked each pedal individually and also changed the cables used and it doesnt go away. 

I also checked if its a power supply issue, i run a t rex fuel tank chameleon that powers all my pedals, the 18v jack i have used a daisy chain to hook up 3 pedals, a Fulltone OCD, and the 2 eq pedals, i checked the power draw on each and it is wayy within the required power that is given out of that 18v socket. 

Please help, this is recent, i never had this problem before. I've gigged with this amp on a few occassions too, noithing was noticeable, and with this issue its very noticeable on low volumes as well.

Hey, 

So this is my first personal all valve amp. Ive had a few around but never one of my own, i know how to use them and what not to do, but ive never owned/played one long enough day to day to realise if the tubes are not properly working. 

The other day, i turned on my amp (It's a 110 volt made for USA mini jubilee head that i run through a transformer at 230 volts mains) as usual, and after i let it be on standby for about 10 minutes, when i turned it on, there was no sound. I proceeded to turn it back on standby and check all my cables in my signal chain on my board, and turned it on again (this happened a few times, maybe 4 or 5) and still no sound. 

I then checked the back because i do connect some pedals in the effects loop, and to my shock the speaker cable wasnt connected! (someone must have moved it around while cleaning and i never noticed as its on the back flush to a wall) 

I immediately turned the amp off. and then connected the speaker cable of my cab to the right speaker out, and after a few minutes, started up the amp, after giving it a good 10 minutes on standby. It worked! and the EQ was reacting normally, everything seemed fine. I had friends over so didnt really sit down and check in depth or notice anything off tone wise. Plus it was running on fairly low volume since it was late. 

It's been about 3 days, and i played yesterday, didnt notice anything odd. But today, i feel the overall volume the amp is giving out is really low compared to before. and i know this amps clean isnt really super clean with humbuckers but im feeling like its breaking up way too much and quickly as you turn up.  Could it be that i busted a power tube or pre amp tube? The amp is a year old and played fairly reglarly and gigged only 10 or so times. 

Any help, advice on the matter will be appreciated! Thank you in advance!
