Diezel VH4 2011 Blueface (Reissue) https://reverb.com/item/85852679

The seller directly wrote that the amplifier had been modified. It's really sad.

"Not quite like that." means it's not enough to take the datasheet's parameters and divide by two... I suppose it was clear. Anyway. You're making it up out of the blue. My question is simple: how to measure the Raa of a specific output transformer. I don't need wiring counts, core specs, or...

Please quote me where I tried to argue with you. You suggested using the data from the datasheet, so I wrote an example to show that there may be small differences within certain limits. Then you repeated again that in order to get data about a specific transformer, I need to have it. And so the...

Alright, I've got one. What should I do next? How to measure Raa?

Agree... I have been looking for information about Blueface for many... years? Hope we will get closer to understanding it one day.

What evidence do you have?

Not quite like that. Based on the reference data, we can get average values. However, Raa may change slightly. For example, take Hammond transformers: > (15W, 2x6V6GT) : 1751M (8k) and 1760E (8.5k); > (100W, 4x6L6GC) : 1760W (2k) and 1750D (2.35k). Or Hammond 1750U (1.7k) and ClassicTone...

Hello everynyan! Does anyone know the specifications of the T100-152019 transformer (such as Raa value)? (not SC-152019B) This transformer has a power rating of 100 watts and belongs to the Mark II series, specifically non-Simul-Class version (Mark IIB, I believe). The amplifier features four...

Well, well, well! When will you compare those amplifiers? I really want to hear it! :)

Make Diezel Blue again!! ?

I thought the same way... But maybe there's something else? For example, a shorter grounding wire to a "main caps star" (in terms of Marshall) - and is this more important than a long anode voltage line?
