Hi Paul, you can use an adapter betwen 200mA to 400mA. For example I have two different, one with 225mA and another of 300mA. There is no danger to your unit. Bye.

Hello Mr. Collin,
I stumbled across your website when I was researching a BORIS that was donated to our Thrift Shop. I must say that the information you compiled is most impressive!
We try to be responsible in the ways of reselling (i.e. eBay, Thrift Shop, Antique vendors, etc.)
The donation consists of the complete, original BORIS system and is in perfect condition (looks new) along with receipt (purchased from Brentano’s in NYC on 7/22/1979 for $225 + $18 tax), original owner info (mother bought it for her son), warranty card (filled out by son but never mailed in), manual, and typed suggestions from the store (?). The serial # is 012864.
Part of my job is to make sure we are good stewards of our donations. You seem to be a leader on BORIS subject matter, so if you could offer a value for the system, I’d be much obliged. I am waiting on some other opinions from collectors, but your site was very impressive and makes me believe you know best.
Thank you for any help you can offer!
Blessings,
Scott Morris
