The Amp Garage

reducing cathode cap can help on marshall, but I haven't tried it on my express. have anyone else tried it? did it result in tighter bass?

One other angle on this. Though the Express circuit is basically a 35 watt amp or so, the output transformer in the Ceriatone version is pretty stout. More like 50 watt Marshall iron. When I ABed my original Express to a Ceriatone the Ceriatone was definately louder. I'd say if my original Express ...

from the shinrock webpage: Sorry for very bad news. My daughter Muriel, 12 years old, has a tribe brain tumour and is lying in hospital. I have all orders and will ship them out as soon as possible. I will take no new orders, I will answer e-mails , but I can´t promiss in 48 hours. With best regards...

6k6 might work

12at7 in PI/V3 works very well. these are cheaper than 12ax7s as well.
NOS suggestions: Mullard, Siemens/ITT lorenz

I tested a bit today. here's what I would try:

1) ecc81 in V3
2 ecc81 in V1

So do you need double the bypass cap as well to retain the same freguency boost?

I have the same question

jj 6v6s should be safe IMO

yes, I liked the ecc81 in V3. the 5751 in V2 was ok, but not great. too smooth for me. not aggressive enough

try this:
v3: ecc81/12at7
v2: 5751 or 12at7
v4&5: kt88 or 6550

the ceriatone will sound better after break in - it was new

does ceriatone sell cabs?

yes tdpri
