Just purchased a Carol-Ann OD2 100 watt (6L6) model from Cyndicate. I removed the Chinese preamp tubes, and installed a Tung Sol in V1 - LPS's in 2 and 3 - and a 5751 in V4 PI. This is the most incredible sounding MV amp in on the planet!

I'm using a Klon Centaur at 9:00 (gain), 11:00 (tone), 9:00 (volume). The Klon acts as a mid boost/compressor. I can't compare the OD2 tone to anything really? It's a completely new sound as far as my hearing is concerned... I like that!
Thanks for the kind words !!
V3 is really biased for a 5751. The higher current tube is better at driving long cables in the efx loop....but hey if you have success and it works great for you how you have it, then I aint going to argue with that !! 5751 in a 6L6 PI works well, expecially if you want to kkep the ratio of preamp to power tube distortion favouring the preamp.
I was reading the manual last night, and I noticed that the 5751 does go into the V3 position. I don't know the year of the amp, but I suspect it's at least a 2009? It looks mint! The left-side transformer gets a little warm - but I suspect it's acting as a sort of heat-sink to the 6L6 tubes? More to the point: I was wondering if I could run a quad of EL34's in the amp, and just re-set the bias? I looked inside the amp ( I won't post any pics without your approval), and I noticed that it's loaded with 100K screen resistors. I'm wondering if this was originally an EL34 amp, with 6L6's loaded into it? I'm use to seeing 470 resistors in 6L6 amplifiers. Is there anything I can look for in terms of components that will tell me if it was originally constructed for EL34's? I would just submit the date-code, but the amp has no model number in its respective block - and no serial number in its respective block either. Lisa sent me plenty of info, and I do want to thank her for that. She mentioned that the later transformers bias can handle the EL34 power tubes... I'm hoping that this is the case with my amp. It sounds incredible with the 6L6 tubes - but I just love the "cut-through" attack of EL34 power tubes!

I took plenty of pics, and also made a video of the interior workings of the OD2. Again - I will not post any of these without your approval - ever! If I need to send it in - I will. I'm thinking that the amp may be new enough that it may have already had a circuit update done?
I've owned Guytron, Zinky, Cameron/Marshall, Cameron/Carlsbro, Cornford (great amp!), Fortin, Bogner, Bray/Marshall... The Carol-Ann is it!

A REVO is next.
