Mercury brands marked with Plus+™ logo are cloned transformers with minor additions. You’ll only see the Plus+ logo on our ToneClone, Partridge and Radiospares catalog listings. They’re modified, without tampering with the original tone, to match today’s power company voltages and employ better noise immunity.
Variations include: added input power taps, added secondary taps, and other minor enhances to the originals. More good news — all Plus+ transformers come with both our 10-year Workmanship Warranty and Tonal Guarantee.
To find out more, or discuss to the characteristics of the different transformers sets available for your amps, give us a call or email.
