Sounding good is better than looking pretty.

Sounding good and being safe enough not to injure/main/kill small animals (incl. children) is a bonus.

Yes. And when I’m upstairs on 3’rd floor If Sam has left Roxy our Staffie shecomes straight upstairs to see me. So its a plank of bamboo relay ...

Thanks

Now that its all Octal barr the GM70……

Thanks!

This is probably a good time to say. I’ve come to realise I cant make any amps or power supplies into boxes. My left hand has a long way to go. Though I need to use it its baby steps.

So what Ive decided to do is buy more octal relay bases and use only octal valves, but also the GM70’s. Might ...

Lots of stuff in our pursuit’s are costly.

I dont agree with Sowter when you wind a power transformer you choose the core size by the power only half the centre tapped winding is working at a time. So the current through half the winding is taken into account. The core and A which is the core suface area is measured for that duty. Which is ...

I'm having a moment and can't convince myself I'm correct. With a traditional centre tapped mains transformer intended for full wave rectification, if the whole of the secondary is used with bridge rectification the current capacity of the secondary should be halved (compared to full wave CT ...

I read that sentense sequentially as a dyslexic person well one like me, does. So its good news then bad news. But what was I expecting? Nada. I wasn’t dissappointed.

Im probably better off with my way of designing amps without spice anyway.

Good to know

Too much to hope for EL38

As its monoblocks in one box every filtering section is duplicated.
Plenty of room above the plimsole line for these chokes on top.

And to show the duplicares.

The caps paired with the chokes probably ...

The circuit now Ive landed in Appolo crash and burn.



Oops I fogot that circuit requires 4 PL/EL 38’s.

Queue another picture.

Anyway Major Tom to Ground Control. I have this Chassis, which the 300b amp is small enough to fit in. The R core OPT,s should fit inside. For the off board power supply I have some 400v power transformers which as they arent centre tapped I’ll use two hexfred bridges matching chokes matching caps ...

All ears my spice so far is “no spice at all!”!
