Hello to fellow members,
I've been only reading for a while but it's my first time writing something. I really admire all your work thus come seeking for help.
I have a Primare A30.2 amp and was looking for a way to convert the voltage from 120V/60hz to 220V/60hz. I looked into the schematics but honestly have no idea how to read it. If it's a simple jumper tweaking, I thought I could do it myself so I was wondering if anyone could shed some light before I take it to a dealer and spend $$$.
Thanks.
John

For some "unknown " reason the mains transformer diagram is just shown as a square box --correction ! the power supply unit is a separate item so needs a separate diagram.
One guy with the same amplifier was asked ---"what is your mains voltage" -- 230V AC and what is the voltage of your transformer- 110V AC .
The conversation stopped dead there as he was complaining about a blown amp with 5 volts offset.
A lot of companies do have voltage taps to take care of this I have a feeling Primare has different models for export,if that is the case buy a step-up transformer --NOT from Walmart as their cheapies have only 220 volts output and no you need 230 volts at least for a power amp as it will overheat the transformer ( among other problems ).
More info says its a separate custom made transformer and is original version --shipped with a 230V/50/60cycle transformer but if anybody can supply a circuit diagram of the power transformer unit showing dual tapping for 110Volts then it will save me looking further.

duncan2,
Thank you for the information. I really want leave the step-up transformer as the last resort. I guess before anyone chimes in, I'll have to ask a dealer or a local repair shop to do any type of conversion.

If its a case of only a 230V version fitted then what you are talking about is replacing it internally with a 110V version.
The problem the tech guy will have is its a CUSTOM transformer -IE- non-standard Primare make a big point of this so that means an import transformer unless somebody comes up with the transformer circuit diagram which Primare seem to be reluctant to publish.
The only other way around this is if two transformers can be made up to take its place but will they fit and you still need to know the connections .
I was hoping some Primare guy would come to your aid right away but not so far.
Another idea is to borrow a step up transformer and meter the output AC voltages from the transformer if no diagram can be had.

duncan2,
Do are you saying in order to convert, I have to replace the whole transformer? Even so for the case of 230V? Pardon my lack of knowledge of how to read schematics, but does it not have something like a simple switch with a jumper that will convert it to 230V?
Also, shouldn't the 230V version have some headroom to be operated in 220V as also (assuming the same frequency 60hz) ?
Thanks again.
