Could someone let me know which heatsinks are intended to be used with the 317s on the PSU boards? Thanks!

SK 104/25.4 220 - Heat sink 25.4mm 14 K/W black anodised

Thanks!!! That’s interesting, is that Sil-Pad link to a large sheet that you cut yourself?

 

[oran.outan]

As I remember they’re pre cut...

We are pleased to now stock Lundahl's famous LL1538 transformer.

Price?

EUR 60,00 each + shipping + VAT where applicable

Would you be able to special order some things from Lundahl now? My US distributor retired.

Erhard Audio is now the US Lundahl rep. I just received transformers from them today, and have some on order from Sweden. They were very prompt and helpful, they have some stock in the US for immediate shipment, and can order the rest. Here's their web page: Lundahl

Yes, I have since discovered they were the new dealer and have been in touch with them.

Thanks though!

But maybe Volker could still get stuff if we need it.

Sorry, I only stock LL1527 and LL1538 transformers.

Can you special order?

This wouldn't make any sense. You can order directly from Lundahl, I won't get any better price than you.

Ahhh. OK.

Email sent enquiring about Bo Hansen DI board or possibly partial kit and transformer.

Thanks
