Hi Guys, I have unfruitfully been looking for the schematic of the Larry Moore 6J5/10y/300b amp, without obtaining it. In www.woodhorn.com no longer is, somebody can help me, thanks
Thanks, I don't no, The circuit was long time in the Web of www.woodhorn.com
It's amazing what you can find on the web archive:

My new toy
Hi Guys, Here is my new toy Diy 6J5, 10Y, 300B with some modifications on the circuit of Larry Moore.
The means characteristic of the 300B with crystal clarity of the VT-25 or 10Y, thus giving the best answer in the whole frequency range. For me A dream come true. Thanks, Martin
An externally hosted image should be here but it was not working when we last tested it.

Did you use an input tube or is the VT-62 driving the 300B directly?
Thanks,

Re: Re: My new toy
Hi José, the tube VT-25 now work as power tube in my 6J5 6SN7 VT-25, wow I only say is a great tube, my set 2A3 work well, the 45 is well, but with the 300B I have more problems I do not think anything special, will only fame? I build, 6SN7 300B in cascade, SRPP 6SL7-6L6 and now 6SQ7-6AG7, I dont no with the 300B.

Re: My new toy
Have you had any problems with hum? I see that you have the power transformer and the output transformers lined up with one another. Isn't that a no no?

Re: Re: My new toy
No, the hum level is not problem with 10Y as driver

andyjevans said:Agree - the 10Y is very easy to work with - can be used at very different operating points, no hum. Great tube.
Yes sir, great tube, my favourite, IMHO pity to quit as driver when is an excellent output tube .

Now I build 6J5-6J5-300B type Derek Walton MK amp,
CijTele52 said:I use VT-62 as driver tube. I started with 10Y/VT-25 but ended up using 10Y for another project. So I used VT-62 instead.
Attached schematic show an opamp buffer driving Electra-Print opamp transformer loading to get some gain to VT-62.
