Basically, what is the ideal set of tubes to put in a 6505+ combo (or regular 6505+)?

I am looking for a good metalcore type tone. I would like to have the tightest, most defined, throaty, powerful, punchy palm mutes as possible and overall clear sound with no muddiness and crunchiest distortion possible. I don't like an amp to sound too bass heavy or boomy.


I hear a lot of good things about Tung Sol 12ax7, SED Winged C, and nos tubes.
Would it be a good idea to get one nos tube for v1 and regular production tubes for the rest? Or are nos tubes too much to deal with?

Could you please recommend tube combinations specifically by each position, v1, v2, v3, v4, v5, and also why you recommend said tubes and/or tube combinations?

Any advice is greatly appreciated as I'm new to tubes and tube amps.

If you can afford SED =C= power tubes buy them, otherwise buy JJ's.

In the preamp, if you can afford non-russian NOS, buy them. Otherwise, use JJ ECC83S tubes.

Can you elaborate as to why you suggest SED =C= power and JJ ECC83s pre amp tubes? (JJ pre amp tubes as opposed to Tung Sol)

Any other suggestions as to what tubes should go into v1, v2, v3, v4, and v5 in a Peavey 6505+ 112 combo?

New tubes don't give you a metalcore tone, hope you know.
They can improve the sound, but it will still sound like the same amp, at its core.
The SEDs, or Winged C's, as people call them, are just all in all good quality tubes that sound good.
I have found that Svetlana 6L6s sound very similar.

You're making a pretty big deal about the preamp tubes, which is probably not all that important in a high gain amp. Meaning, a lot of times, people get different tubes to get certain nuances in tone. Since it's a high gain metal voiced amp, you will probably either not notice or not really need such nuances.

Just get JJs, they're good.

What pick ups and pedals are you running? Do you have a tie screamer clone up front?

JJs all the way for this amp. Recommend a 5751 in V1, AX7s in the rest. It'll help tame the gain a bit in the clean channel and make ch 2 and 3 a bit tighter as well.

SED make the best power tubes currently in production without doubt. They put those things in Mig jets.
JJ ECC83S tubes suit the amp. If it was a head I'd say to put a JJ ECC803 in V1 but as it's a combo you can't really do that so it's ECC83S everywhere. TungSols are too brittle sounding for a 6505.

I'll second this recommendation. My JJ 5751 really enhances the tone on the lead channel. It gives it better clarity and punch whereas a 12AX7 there is sometimes a bit much. I also use a JJ 12AT7 in V5 (Phase Inverter). That one really gave some warmth to my clean channel and gave it more headroom.

Though both of those tubes cut the gain a bit -- don't let it fool you into thinking it'll "neuter" the amp. There is still more than enough gain on "4" with most guitar/pickup combinations. Overall, the tone is just sweeter all around. I use JJ 6L6s in the power amp section as well. I haven't compared them to anything but the Ruby 6L6s that came with the amp -- but between those two the JJs literally blow the Rubys away.

Ruby have a JJ too. "Ruby" doesn't tell you what type of tube it is, you have to look at the entire code. They rebrand, they don't manufacture.

SED are better that JJ but JJ are better value for money.

The Migs use valves for everything.

A Russian engineer once told me that he laughed his head off when the West bought the excuse that it was because of EMP protection. He said it was just because they had no semiconductor industry.

On Peavey forums, they were recommending a JJ ECC803s for v2 and possibly v3 and v4, with Tung Sol in 12ax7 in v1 and Sovtek 12ax7LPS in v5. Why would it be better to have JJ ECC83s over the JJ ECC803s? I heard that the ECC83s only advantage is more gain, while the ECC803s have less gain (not much less), but sound better.

The JJ ECC803 has a tendency to be a bit microphonic which pretty much excludes its use in a combo.

They become microphonic in combos while less so in heads?

Combos are inherently more susceptible to microphonics since the tubes and speaker are housed in the same enclosure, often with the tubes just a few inches above the speaker. Not exactly optimal conditions for tubes that tend to be sensitive to vibration.

The Peavey 6505+ 112 combo has a separate compartment each for the speaker and amp components (tubes). Since the tubes are not in the speaker blast zone, therefore my amp shouldn't be susceptible to microphonic tubes, no?

No. That's how every combo works. There's still no real decoupling between the chassis and the speaker like you get with a head and cab.

And this is why I think high gain combos suck. They are ok if it's all you can afford I suppose but it's just a bad format for that type of amp.
