Most of the producers uses dual primary windings (2*115V) on the power transformers and they just connect them in series for 230V and in parallel for 115V. Simple jumpers on the PS boards usually do the job. Knowing Mr. Pass older designs from service manuals he does the same. So all you need would be just to reconfigurate the junpers for 230V.
Otherwise you would need step up transformers. In case of preamplifier the 100Watt one would do the job, but in case of big power amp you would need a monster one.

You should try to get confirmation that the amp has two sets
of primaries that you can put in series. Generally a call or email
to peter@passlabs.com is the way to find out.
