No, it's not. But you could use the transformer in the BTU-2S, except it's B+ will, no doubt, be different and then you'd have to deal with setting up the screen grid and bias for the new voltages.




Great, as long as its doable. Sounds good.

That's 5% high. Probably okay. What voltage is your AC line running at?

I don't think it's a good idea to wire with the tubes inserted in the sockets. If everything goes right it should be okay but one slip and solder can wick up the socket pins and then you've got the tube pin soldered into the socket.
Wow Flip, I never thought about that. Glad I asked.
House AC is 121volts. Remember that my dummy load is still 150ohms light, if that matters.

I didn't like the looks of that transformer anyway, for the transmitter. I do like the circuit.
What does 150 Ohm light mean?

Maybe he wanted 500 ohms ... but he only measured 350... so he was 150 ohms light. lol
.. or maybe he's using a 150 watt light bulb as a dummy load.

Those phono oscillators with 6sa7 not a fan of. The 6888 is the strongest of the multi control transmitters on this site. The 6GY6 one uses less heater current and there is a slew of tubes that can be subbed into it. The 12CS^ one on here is a variant of the 6GY6 type same pinout just more internal grids. One can always add a solid state pll and take it to the entire band.

OK boys, pull up a chair. School time. The suggested dummy load is 15K. I used two resistors tacked together. A 10K and a 4700ohm. They measured exactly 15.15K ohms, go figure. SO, that leaves minus .15K ohms of a load, or 150 ohms light.

And provide heat on a cold night. And some light to work by.

Hey, I wasn't the wise guy cracking jokes :lol:

150 out of 15,000 won't make any difference.

I scored another babe. $32.80 and has a big transformer, and looks like Gort. :wink:

BTW John:
This afternoon I've been saturating my ears in the lovely glow of my 6v6 amp.

It never fails to thrill me. I'm sure you agree. No?

( even running those low-cost ($5) NEW Made-in-China 6V6GT tubes I got on Ebay last year)

Lovely.

You know it Peter. Just remarkable. I really like being able to fine tune it with tone control. I wish Rich would build his 5902 to compare.

Ready to start the preamp wiring now. Any ideas about which part to build first? I will need to pay attention to positioning the big caps, so I can get to the whole circuit in case of a problem. Kind of a dumb question, the small silver paper caps, any polarity to watch out for? I guess no.
I have two conductor shielded cable. OK to run right/left channel in one jacket? Or separate.

Do not you see that price listed there ?

BTW-purchase price $13.50
Shipping $19.30 = $32.80 total


Just listening to some nice classic music my self, amazing. With headphones.
