The strange title sort of indicates that this project that will take some time, is made up in Sweden using Russian tubes (6V6 = 6P3S and 6SL7 = 6N9S).
The reason this amp was planned was a cheap
Chinese PCB holding the simple 6V6 PP-amp found at DIY
Audio Projects
Forum.
Got the tubes, at least the OP transformers and may have the power transformer. Missing a few tube sockets, but just ordered them from Finland. A crazy thing is that different PCBs use different diameters for the socket pins but even if there sockets really don't fit a bit plier-work fix everything.
Have to inspect my component stores, I may or may not have all components. When check the component list on eBay, all resistors except the 6V6 cathode resistors are 1W.
But before cutting the heavy aluminium sheet I have and drilling holes (got a "nice" wooden box), there are several issues I must handle before starting another project. Well, I actually scrapped a 6V6-SE project and a 832 SE-project and an EL84-PP project so I think it is OK to start this one.
The issues and questions:
1. The cathodes of the 6SL7 must be wrongly connected or just wrongly drawn. I marked, in blue, how it must (?) be. Me is correckt?!
2. Got physical small 270R/5,5W resistors. Should work but with slightly lower power OP. Correct?!
3. No big matter, but 620p FB cap ...??
4. The blue figures are from sources that sell the PCB and complete kits. Looks OK?
I have managed to build so many amps that I can say none of the issues are any issues but want to check if anyone else have had any.
I finally noted that someone asked about a potentiometer, using the amp as a integrated amp. I read that and will take proper action, like make sure I have a preamp ready. Else I will sort out the information in other threads before I go.
