What are the other 2 Tubes for if the amp holds 5 Preamp tubes?

You can replace the tubes yourself. On the preamp tubes, they impact all channels. For what you want use an SAG-MHG kit for V1, V2, and the phase inverter. For output tubes use the 6L6S in a 5-6 rating and if the amp has the stock bias these will be plug and play. If you order off the GT website put in a comment asking for a 5-6 rating only. Kool, Thanks alot. For the power tubes does the brand make a big difference? You can get the 6L6S from many places but it is a specific type of 6L6 (JJ) but if you want to get a 5-6 rating, only GT has these ratings from dynamic rather than static matching. If the tubes come from another source you will need to check the bias and probably have it adjusted. Sorry for the many questions, but what is a good price range I should be paying on the power and preamp tubes, I don't want to be paying too much for them when I decide to purchase them. Also regarding the pre-amp tubes, the kit is only 3 preamp tubes, but the amp holds 5 preamp tubes, so what do I use to fill up the other 2 spots? Thanks Alot

Hey Myles, I just picked up a 5150 head for a really good price locally. However the tubes in this thing are some no name thing. I basically need to re-tube this thing. What tubes would you suggest I put in this thing for playing mainly metal and classic rock on this thing. Also is there anyway tubes can affect the rythm channel also? I never re-tubed an amp before, so is it just as easy as pulling the tubes and replacing them? Or is it much harder and should I take it to an amp tech?

Hey Myles! I need your enlightment! Never asked you a question before so this would be a first hehe. I have stumbled across a few gain control boxes on ebay. Heres a link to one. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=38074&item=3734340774&rd=1 I was wondering if these work really well on tube amps? Also does using these do any harm to the tube amp since its cranking it up so high to get the tubes running. Well Thanks for reading this. See ya.
