Hammond 290MX Vox AC30 Reissue Dual-Primary Power Transformer

The 290MX is a Hammond 290 Series power transformer listed as a replacement for Vox guitar amps. The part page gives AC30 Reissue as the amp model, and the VOX section of the ordering table lists it for the AC30 60's Vintage Flat. The short description reads 2X120V PRI.TXMA, AC30 RE ISSUE.

Its dual 120V primary is rated 120/240 VAC 50/60 Hz, and the ordering table lists it as bobbin wound. The ordering table also notes that no cover end bell is provided with this part, which matters if your original installation used one. Secondary voltages and currents are not published.

Hammond designed the 290 Series for drop-in replacement of original units, with parts made to look similar to the original factory transformers where possible and materials and design specs kept as close as possible to the original part to preserve the stock tone.
