Hi guys. Long time, no post.

I've just bought a very tasty gtr reverb from the States on eBay. It is an Electro Harmonix Cathedral Stereo Reverb. My Q.'s are in relation to the transformer required to power it and my other pedals. Because this had been purchased brand new in a box, the included transformer is a 120V AC model, whereas household power here in Australia is ~240V AC, at, I believe, 50-60 Hz.

The included transformers stated specs are:
Input: 120V AC 60Hz 0.15A
Output: 9.6V DC 200mA

I have available a number of candidate transformers, including

1. Input: 100-240V ~0.3A 50-60 Hz
___
Output : 9V ---- 1.0A This is a very common type of transformer which will power most any Boss/Ibanez/Behringer etc. stomp box.

2. Input: 240V AC 50Hz

Output: 7.5V DC 100mA This used to power a contact lens ultrasonic cleaning machine.

3. Input: 240V AC 50Hz

Output (1) 10v DC 400mA
Output (2) 8V DC 200mA This is a dual output device which used to power a cordless phone base station.

But, noting that No. 1 above has a minimum input of 100V and a maximum input of 240V, I am wondering if I could use an international power adapter to use local 240V power through the Electro Harmonix supplied US type transformer...after checking with a multimeter that the end result was actually 9V DC.

However, I don't want to fry anything inside the new pedal, or any of my others. The alternative is to buy yet another transformer of exactly the specs required by the EH pedal. Or ideally, one bigger tranformer with capacity to supply power to all of them...about half a dozen Boss/Ibanez devices including a Boss Line Selector, TU-12 tuner, Tube Screamer, the EH above and possibly a Boss '59 Bassman box coming soon.

Your opinions?

How do you guitar guys with similar power supply needs manage?

Thanks for all responses, John
