Connections are very important spots, so make sure they are 100% good, in most places You can solder the wires instead using the screw connections.
In some free time I have made a smallish input board. Just one transistor + one bulb setup. Needs a bit more work but works good. I do not need a lot of 0,00000x% to listen to the music anyway 😀

Not that new but very good value for money. 2Gs/s and bode plots are coming with it. Recommended dsox1102g 😀

Every day brings something new. Recently I found out that ''worse'' can be better than ''good stuff''. I would buy some nuvistors instead but there no nice dimm light coming out of it 😀
Have you got in mind any miniature tube which will work OK in quite smallish anode voltages ??
I only have 6N16B and some 6N28B in stock.

I couldn't sleep two days ago and had too much time for thinking so yes it is a new idea. I am just playing with some resistors values to get the best results. The thing is that with some ECC88 tubes it sounds quite bad but some other ones are playing really nice. Today I have made a small converter board for 6N16B tube.

I think that there are some 6N16 in my stock😉
If you ended up with some interesting results may be i can follow.😎

I am just drawing a PCB for 6N16 so when Ill finish it up I will post the files.

I don't have any better idea for a compact tube than 6N16B 🙁
But this one runs pretty well, right?
What rails voltage are you using?
Thanks Peter!
I use the photo resist method only!😉
What about the sound of this new IPS?😎
Valery
6N16B runs really good in this circuit, voltage rail is 42VDC, grid at -0.8V bias approx 1.4mA per single triode.
thimios
Sound --> first impression, does not sound as valve amp anyway. Good dynamics with powerfull bas kick, rather quick bass response with a bit thin body at the lowest Hz end.
Midlle are nice and clean. Top octave goes a bit forward and it looks like it is not so precise as transistor version of the amplifier. Overall i like it.

I hope that we don't speak in a wrong thread...
Nice,i will make this, i have some of these sitting unused.
Thank you that you give me this opportunity!😎

The Leach Amp v. 4.5, by W. Marshall Leach, Professor.
I built two identical monoblocks. Great sounding amp. The enclosure was bought on ebay (all blank - I had to drill all holes). The front panel writing was made using Letraset and then lacquer sprayed for increased durability.

Hello Mitchel
Nice amps, one of my many projects is my Leach 4.5 (may he RIP). My PCBs are some what bigger, basically the same layout as yours. I'm not sure what size of angled aluminum to go with for the outputs. Great job!
