Up until recently we have been laser etching the Zen Dragon on the back of the power transformers on all SE84UFO25 amplifiers...
Due to supply problems, we can no longer get the special paint that we used to paint the transformer and have had to switch to a different type of paint. This has made it impossible to get consistent results with the laser so we have discontinued the process of etching the Dragon on the rear of the power transformer.
Instead, we have moved this makers mark to the bottom of the amplifier and printed two of them to match the ones in the foam lined case for the tubes.
