Will be purchasing more of these

by anonymous

This is the Heyboer 6179 18W Power Transformer. Made in Michigan USA. Phenomenal for an 18W build. Comes with a single end-bell for traditional laydown chassis mounting. I mount mine standup-style using the end bell conversion pieces from Heyboer. Works perfectly with a 6CA7 / EZ81 rectifier and also with 1N4007 diodes. Powers 2xEL84, 2x6094 and 2x6973 output tubes nicely. Will be purchasing more of these. Mojo offers the best pricing on these particular transformers of all the distributors I could find. Would work with 240VAC or 120VAC input to the primary side, I have only tested the 120VAC tap and they work perfectly in the US.

my "goto"

by anonymous

The Heyboer transformers are my "goto" transformers for high quality guitar amp builds. I've used a variety of their transformers and Mojotone is an awesome supplier of their product. If you want to get into some amazing 18 Watt tone heaven, get the Heyboer PT and OT.
