I just verified with some friends, they know Piemme Elektra and are very satisfied also for this brand

I haven't direct experience with InMadOut but I've read lot of times good feedbak about those transformers

There Is no problem

.... I think a traditional fixed resistor. Why switched? I mean that the pots on the schematic, that are swapped using a switch, are acting, one at a time, as grid leak resistor ... You mentioned 6Av6 before power tube. Is there a reason for choosing this over a 12AX7 or AT7 or AY7. I told 6AV6 bec...

Switched pots used as grid leak resistor ?

I'm quikly reading that thread and I've find something that is not favourable to me https://ampgarage.com/forum/viewtopic.php?p=120509#p120509 That preamp has not enough swing for a tube as 5881 and so I think the same for the GU50 or 1625 tubes EL84 is in the order of 11.3mA/V, 1625 is around 6mA/V...

Seems that something is at page 5

a Mini HRM Schem & Layout from 10thnx (I think he is Tubenit)





Thanks

Ciao Guy77 https://ampgarage.com/forum/viewtopic.php?t=10913&postdays=0&postorder=asc&highlight=hrm&start=0 .... Page 2 has a layout you can use Unfortunately on that page I can see only a Schematic https://ampgarage.com/forum/download/file.php?id=11726&mode=view and a link to a pdf containing one ...

Thanks Guy77

Is there a version of Layout I can use

I'm interested also if it is only about the preamp or a whole amp Layout from which I can borrow the preamp layout

Ooops ... Sorry Reeltarded

I would like to plan an SE amp using a GU50 (or 1625 as Power Tube)

Please can you point me to an ODS version that has good documentation to plagiarize the preamp schem and Layout part

There are so many versions of schematics and Layout that I'm a bit confused

Many Thanks

if they hadn't had any problems they would have saved the cost of the wounded ones, since they had put them on, they would have had some reason, don't you think ?

I use Visio (an old 2007 version) for my layouts

and FidocadJ for my schematics (a free program with tubes on library and is very easy to add your own components to the library)

very easy to learn to use

you can download it here
