My MAX1771 design can probably be pushed to that. Yes, C4 & C6 would have to be higher voltage and R2 changed - the PRC221 range have a working voltage of 200V but are safe to 500V - it would be better to find a 2512 footprint resistor with a 300 or 350 volt working for long term reliability.
D1 would need to be changed from an ES2F to an ES2G (same footprint, 400V Vrrm) but it may be better to find one with the same footprint (SMB) which has a higher RMS working voltage. A lower ESR FET would also be a good plan - see the web page for details - https://nick.desmith.net/Electronics/NixiePSU.html Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
