Elekit TU-8600R 300B (and Tubes)

RafaPolit · 11th April 2019, 05:57 AM

So, now that the store has this available, I was (as always) wondering if this would be the right path for me.

Given the price difference to other DIY kits, this requires further thought and research.

So, first thing first: where would I get tubes for the Amp?

Living in Ecuador, it's not like I can go out to the next door store and get a set.

What are our options in the international community? Could we expect the store to have some tubes as a kit (or even as part of the same kit) in the future?

Thanks.
Rafa.

As a second question: if the ACA Amp camp amp with a 19v power supply (5W output) was able to drive my 4Ohm 87db efficient Totem Rainmakers, could I expect the 9.2W from the TU-8600R to afford, at least, a similar volume? Or are 'tube watts' (if that even exists) different and, specially due to low impedance, the 9W would prove insufficient?

Herb said that his similarly speced LS50s were good, but not great.

I do have smaller 8 Ohm Totem Kin Minis, that could be a better match, but then the Amp would seem a bit overkill for the $500 speakers.

What are your gut feelings about this? Thanks a lot,
Rafa.

W = (V) x (A)
I can't imagine that tube watts are any different than solid state watts.

I seem to remember hearing that it takes about a 10 fold increase in watts to double perceived volume. I'm not too sure about that one though.

Hello. For Elekit TU-8600r. Can someone tell me the headphone output Jumper positions? There are jumper positions 1, 2, 3, 4. Which headphone impedance do they match with? Thank you.
