Greetings Fellow Tubephiles,
I am new, so please be gentle.
Can anyone recommend a 50+WPC kit or design (ideally schematic, parts list, and layout) that has great sound?
By "great", I mean those subtle tube euphonics of sweetness, clarity, and openess.
Yes, I'm a newbie, but have successfully assembled a preamp kit, and am currently building a Marchand tube crossover. In other words, I can follow instructions and troubleshoot a proven design, but am not ready to start from scratch.
I also realize that a lower-powered SET amp would be an easier build, but need the power. I am willing to pay for quality, but not boutique, components. And I am willing to pay for the design as well.
I'd really like the challenge and satisfaction of DIY--can you help me with a strong recommendation?
Thanks, and Happy Building,
George Ferguson

How about this one? Would be quite expensive with all the transformers in there...
Or this one...with a little more power (dunno exact figure)

Hey Bas,
Thanks--that is exactly the sort of suggestion I am soliciting.


It looks like the design is from K&K, a retailer
of Lundahl transformers, and specifies which
of their products to use. That's great, and
very helpful to newbies like me.
Can you, or any others, comment on the quality
of this design? Given that K&K seems to be
an established dealer, and Lundahl a respected
brand (correct me if I am wrong), is it reasonable
to trust this design?
Have you had any experience with it?
Is this a fairly straighforward, proven design,
which should have great sound?
Thanks for the tip!

Best,
George Ferguson
Hi George,
I'll try and find out more links for you..but best would be to ask Kevin at K&K...he can then refer you to the people that built his design..

DrDeville, what sensitivity speakers are yours? If relatively high (>97dB) than all that power is not necessary for high volume.
what sensitivity speakers are yours?
Hi Dmitry,
Greetings to you in Russia! Thanks for writing in English, for my Russian is very bad.

My speakers are very inefficient (86 dB), and 4 ohms too! And I love them. Otherwise I would be glad to warm up with a nice single ended triode.
Actually I may build a SET eventually, for when I tri-amp I will be able to use one on my tweeter.
Thanks for your message, and best wishes,
George Ferguson
