Nah, Jimi covered it and made it his but it is Dylan’s song.

Apparently Dylan preferred Hendrix's version to his own.

I've just heard Bob Dylan, Jimi Hendrick, U2 and Neil Young's version of the Watchtower. Whilst they are all good, I prefer Dylan's original version. :relaxed:

I really like the way Tomas used switches for external supplies. Leave the switches up and the internal power supply provides 6v to the heaters (with a 16 amp limit!) when I turn on the amp. If I flip a switch to the down position it uses the external power supply. Not only does the switch provide great tactile feedback but it allows me to keep the external supplies turned on. When I flip the switch back to the up position the circuit is broken and the supplies don’t put out any power. When you use an external supply with a socket adapter instead of feeding the amp directly the supply provides power until you turn it off no matter what state the amp is in.

One of my supplies can go up 30v and the other up to 14v. I’ll probably get another one of the 30v versions. Not only does it go higher, it’s easier to set and is a little smaller too.

Reminds me of the days of Feliks Audio Elise where were using external power supply to heat 12v drivers. Up until recently I still have that but I threw them away.

On the Glenn OTL amp that I had, there is a switch to select 6.3, 12.6 and 25.2 v drivers.

I already have some 11n7 and 16gk6 that I will try. Will eventually track down some 13d1 as well.

What's on the menu for this month? Tomas' personal build correct? Very much looking forward to seeing what he comes up with for himself!

That is correct! But is somewhat delayed because of transformer issues (again but not Monolith this time). But mostly because I need to slow thing down a notch. It became too much stress for me to first work 100%, have time to workout, hang out with my girl and also push one amp per month. So, from now on I'm building 2 amps every 3 months instead.
