The covers are taller than average and the top is domed. If I get a reason to go inside that amp I'll get you a better shot.

I did find a mention somewhere on here that the Toshiba 2N3773 was actually a relabled 2SD873.

Have you any thoughts on the sound comparison between the JLH 10W Class A and the Circlophone based on 2N3055 outputs ?

if they are genuine toshiba devices (which they look to be) relabeling them from a 2SD number to an equivalent 2N number would have opened up a US military market for toshiba.... one thing about Toshiba is that they have a very comprehensive reliability tracking program, which mirrors reliability programs required for supplying US government contracts.

Yes one, the circlo has better dynamics than anything else, but tringlophone is more accurate. Tringlophone will best that jlh due to power circuit. I had minor tone trouble with my circlo although it did everything else optimally.

So even the humble 2N3055 can perform very well.

What makes the circle so dynamic ?

very nice to see the history and age behind some components, since a lot of peoples think they use state of the art , new technics and respect for the inventor.....
