This is a very cool early 1950's Harmony 8418 THC amplifier in fantastic working condition.
The innocence and simplicity of 1 control and 3 tubes = GREAT sound. All original with the exception of 2 newer capacitors, with a couple of very old (possibly original ?) valves.
Tube configuration is as follows: 1 x 5Y3, 1 x 6V6, and 1 x 6SJ7 through the original 6" Speaker. This amp appears to be all original except for the 3 prong power cable & 2 caps mentioned above.

The original leather handle is broken & held together (only just) with some gaffa tape underneath.
Its original transformer is in place so you’ll need a small stepdown transformer for use in Oz.
Most student and entry-level amps from the 50s were abused, mistreated, or poorly stored, so it is extremely rare to find an example this clean and original. And how good is the very funky silhouette of a hollow body guitar on the grill cloth ?
You can spend a lot of $$$ on a tweed amp from this same era, or get practically the same sound from this little gem for a fraction of the cost.
Nice and clean down low, but crank it a little and it goes all thick & creamy with rich harmonic overtones – a fabulous recording amp.Fully tested and ready to go!
