Having just acquired the MK2 version yesterday, my Dorado MK1 PSU TC7320 is up for sale
Complete with the original packaging and a 16v serviceable charger. This is the version with switchable 12v/16v output. Of course you may wish to get Stan to send you a Beresford charger or opt to add a (for example) Swagman LPSU. That may be an option for me further down the line.
Asking £50 plus postage to a UK Mainland address; happy to post within the EU at cost.
