I posted this in another thread but here as well in case it gets buried!!

My beloved CB160 drag bike! Just a bit more than 9 CU IN!!

Solid aluminum billet angle stock for rear "shock"!

Bug Sprayer gas can and the straight pipes were from my Mom's Electrolux Vacuum Cleaner!!!

I couldnt afford anything back then!!

Matter of fact I could have bought (2) of these back then for the price of my Mainline today!!! LOL!

Hi,

Does anyone have experience of the Saratov Silver Shield 6C45Pi in the Mainline?

Hi, I found this adapter, 5842->6c45: https://www.ebay.ie/itm/304698401779

It opens up access to Raytheon, Amperex, Sylvania, Mullard, and even affordable WE on Mainline.

Is it safe to use? It is not the only such adaptor

Roon -> Raspberry 4 -> Khadas Tone in Bottlehead Crack+Speedball -> detachable cable modded DT880

Is it safe to use?  Probably, and sound will come out if you use the adapter.  I'm not generally a fan of using adapters like that with high Gm tubes, but YMMV.

I think what you have to consider is that we have experience with the 5842 and it would have cost less to put the 5842 into the Mainline, but we didn't do that. 

The 6C45 has not quite twice the transconductance and a bit more gain than a 5842.  This makes the 5842 not particularly well suited for the output transformer in the Mainline, and the lower gain isn't particularly helpful either. 

For 5842 use, you can check out the Soul Sister preamp design in Valve Volume 4 1998 for reference.
