Hi John,
I, of course, checked your site first :-) Unfortunately, both meanwell T60C and S210-7.5 are no longer available (obsolete/end of life products).
Regarding the T60C. I don't see in the datasheet that the +/-15V can be adjusted. How do you step the voltage up?

Price are $22 for the TDKLS50-15 and $68 for the RSP-200-7.5
