6V6 SET amp with 6SN7 driver - Page 2

camotecue,

You have high efficiency speakers. So, triode strapped 6V6s will be fine.

Build a stereoblock from the schemo planet10 provided. Save the extra 6SN7 for the future, but you will replace the 6V6s long before the driver wears out.

planet10's schematic and my link are the same , ... the link i posted earlier gives you some background into the design process and construction, .. always useful for beginner.

cheers

thank you all guys for contributing to my query. it may be difficult to find 5Y3 tubes here in the Philippines. can you please help me design the power supply of the triode strapped-schematic as posted here in this thread by using 5u4g tube instead.

6V6s are great tubes, better than those christmas-tree-light 6AQ5s! And they can easily handle 12W or more dissipation (5W audio in pentode mode)

hello shifty! can you please post the schematic of your pentode mode-design so i can compare? did you use 6SN7 tubes also as the driver and 5u4g rectifier tube? thanks

6n8=6sn7

camotecue, we have soooo many 5Y3. you just need to look at the right place, but if you like i can buy for you (cheaper, he he)

5U4 and 5Y3 are pretty much the same, 5U4 has a 3A filament and can handle more B+ current. If your 5V filament winding can handle it, you can plug a 5U4 straight in.

Sorry no schematic, but the 1/2 12ax7 -> 6v6 posted earlier is pretty much identical. Just change the preamp anode and cathode resistors to suit 1/2 a 6SN7 instead of 12AX7.

ah ok sir! please help me buy a 5y3 tube. i'll start buying the parts for the amp.

5Y3 drops 60V compared to 45V of 5U4. in my 45 amp it was quite critical and i needed the 5Y3 because i goofed in the power transformer

camotecue, how many do you need? 2 pcs?

i think the single ended triode strapped 6V6 amp schematic in this thread requires only a single 5y3.
