I would like to know how the sound differs from the 50w other than just being louder.

This is from the Layout Thread.

The two trimmers on the main board get left alone? thanx 


The right hand trimmer on the main board is the one that controls the OD channel level and is the one you'll experiment with most. The PI trimmer (left hand end of main board) is set and forget The trimmer on the satellite board that contains the FET, controls the level for that input. Most owners don't use the FET input much but you might want to just set it to a sensible level and leave it, I have mine at 9 o'clock.

Great Information! I think I am just going to have to play it more to decide on the gain. I have read alot of information on 6L6 tubes. Their seem to be a wide array to choose from. The JJ's I got from Nik sound good-just not sure if there is something better? Some people seem to think that the preamp tubes make the most difference and that the power tubes are only noticable at higher volumes. What are your thoughts?

O.k.- I think I will snip the cap on the volume as I have read several people say they have experienced smoothier tone at lower volumes. I have not  moved the trimmer yet. What do you have yours set at? 

O.K. here is an update. I put in 3 new EH 12AY7 and now have excellent clean tones and more headroom with my strat. Now I getting closer to the sound I am looking for.  Do I really gain much from snipping the cap on the volume control?

Thanks for the advice. I ordered my tubes from www.torresengineering.com. I will let everyone know how it turns out.

Hey guys sorry to ask a dumb question but do I change all 3 of the preamp tubes?

I looked at some information on 12AY7 tubes and there seems to be some differences in the types of Tubes. For example, The GT 12AY7 says that there is only a slight drop in gain where the EH 12AY7 decribes a much lower drop in gain with smoothness. Please let me know what 12AY7 you recommend?

Thanks,
Danny

Thanks for putting that in simple terms with easy instructions. I suppose I am like many folks here that has never worked much with the internal parts of an amp. I appreciate the words of caution about the voltage when opening up the amp. This has been very helpful advice and I will change the tubes and tweak the trimmer and see what that does for me. I am not trying to copy anyone tone because we all know that is in the fingers but I do like the clairity and sweet overdrive of Robben Ford and Tomo Fujita.

Will I need to rebias the amp after changing tubes?

Many Thanks for you tone tips. I have a later one from Nik that has the zucker mods but it is more gain and not as clean as I would like.   I think I will give your suggestions a try. It sound great with my Les Paul but I am having a harder time with the Strat Tones. I really do not want to alter it too much. Do you have any before and after sound clips?

Thanks,
Danny

I just wondered if anyone has played a OTS next to a Fuchs OD30? What was different ? Please give us details.

I ordered mine April 6 and recieved it today. It only took 3-4 business days to recieve it one it shipped. I am still working on settings but it sounds great so far. 

Mine Shipped today as well  Finally after 12 long long long weeks!

I am in week 11 now and Nik Emailed me it would ship Friday. 3 days is not bad at all. Thanks for the information -I am looking forward to getting it!
