Hello everyone,
I'd like to know if the are any news about the next realization of TU 8200 OPT upgrade from Lundahl??
Some time ago Mr. Per Lundahl said:
"...With the LL2783 (for Elekit TU-8800) we had a new challenge as the amplifier self-oscillated with our first transformer version. In LL2783B and LL2783C we managed to find a different winding structure which eliminated the oscillations. (LL278C is the final version for TU-8800. It sounds very (very) good. I should have stock in late February)
As far as I understand the modified TU-8200 amplifier has a similar topology and behaviour. I expect that the same winding structure could be used for a TU-8200 replacement/upgrade transformer if this would be of interest. "
Thank you

TU-8200's chassis is too small . It is very difficult to prevent the interference from the R-core.
The only option to make the opt similar to the structure of LL2783C.. Unfortunately, the cost to make LL2783C is very costly. The cost will not add up.
So I recommend you to look at TU-8800. IT is a very good amp with LL2783C.
