VTTC feedback network comparison!

excellent work, those arcs in the last demo where crazy big, you could hear a certain total quality to the audio tho that suggested the tube was stressed, i get that sound with mine to when ime red plating. Cracking work, very nice coil indeed, i wish mine where that tidy.

@@lukebowers536 thank you!😇 Yeah its really crazy how far these tubes can get pushed over the Limits. Also how much more current the tube is conducting at its thermal limit. But its a really narrow path on the edge to push it that far😅

These arc are awesome real big is that a GU81? I would really badly want to take a look at the scematic you have used!! Could you do us all a favour>?

[@marvswelt2587]

@@jonaoconnor8065 thanks!🙂 its the GU81M There is no scematic now for this. And i change things all the time to optimize it more and more. But yeah for sure, when this project is finished, i will draw a scematic and make a video with/about it🙂

How much power in full nurst mode?

[@marvswelt2587]

At full Power without staccato, it will draw about 5-6 amps on the Mains...about 1200watts with the "hottest" grid feedback configuration.. With the normal and most efficient feedback circuit, it draws around 950 watts
