low power class A/B options?

[Aquila Rossa]

You're confused about 'one output tube' and 'single ended amp'.

Nah. As you may see from my OP "of either single ended or A/B" i do know the difference.

You said "This is because you need push-pull to develop the conditions for the B-load-line. This infers that you have two tubes operating in opposing phase to begin with", which is not correct because it can be done on two triodes or pentodes in a single tube, so who is getting confused .

A dual triode (or dual pentode) is effectively 2-tubes-in-1. When you use a dual triode in a push-pull output config, it's pretty much two tubes sharing a common heater and glass envelope.

nice way of describing it. wwhere is the like button or post voting function.

I only have limited funds of just over 1k. Not likely to have this kind of money again any time soon, due to being so crook. I am torn between building/buying a amp, buying a set of studio monitors, or getting another guitar. If the sheer power of G.A.S is the motive the guitar option will win (another SG). The amp or speaker options are more practical.

Aquila - I can't tell what was in your original post M8 - it seems to have morphed slightly from how I remember it. Never mind.

no. an edit record would show on it if that was the case. yeah, never mind. i was just joking with you anyway.

I'll get back to this thread when I stop dilly dallying [sootying] about how i want to spend my money, and if the amp option wins.

I have some 6DZ7 valves (which are two EL84s in one octal tube the size of a 6L6).
They are designed to use as a push pull output for a very compact amp.
The cathodes and screen grids are commoned inside.
They could be used for any circuit which calls for 2x EL84.

Nice!

Want some to play with Ryan?

My amp runs on 6DZ7s, two of them, well it did, at the moment it's on 6L6s, but it was designed for 6DZ7s, cool tubes, mine are nationals, and they aren't as expensive as some NOS tubes!

Obviously it has a switch to change between the tube types!

What kind of amp is it?
Do you know how the output impedance changes (speaker matching) when using 6L6 switch?
I would be very interested in seeing that amp.
I have 8 NOS National 6DZ7s.

[Eruera]

Could high power el84 amps be made with those fellas? Like the equivalent of 8 el84s

Certainly, but because they (6DZ7) are no longer made, replacements would be a pain to obtain.

My amp is a custom, bilt just for me, essentialy the front end of a DR-Z route-66 into the 2 6DZ7 poweramp, SS rectified, not sure what you mean by change in output impedance between the diferent tubes, it's got a 4, 8, 16 and 2x 8 wired in series speaker outputs.

I'm not a techy about all that stuff, it puts out 32w watts within a couple of decimal points before clipping, the 6L6s have more bottom end, but not so sharp on the attack, so sound cleaner than the 6DZ7s, but both sets of tubes sound awesome, but obviously, I'm bias!

the proto type had 2 EL84s and was tube rectified, but we decided to go with SS for convenience, and the 6DZ7s to double the output but save space, and because they're a little different.

the 6L6 option was added in case I can't get hold of the 6DZ7s one day!

the tube store currently have them, not a bad price, but who knows for how long!

If you have an amp you like and want to go the home studio route, do the following:

1. Get a load box with a line out. Many available attenuators and the badcat unleash will serve this purpose. it's best that the load is reactive.

2. Download Two Notes Wall of Sound. For free. Basically it's the software component of this: https://www.youtube.com/watch?v=8Mn9116AxiE

3. Buy a couple of two notes cab emulations to taste. I recommend the rack hero greenback cab.

...And you'll have an excellently mic-ed version of your amp's tone at bedroom levels.

This approach will allow you to build the type of amp you really want, rather than build to the volume you need. If you really want a 2xEL34 amp, you can do it.

WOS also works for improving the crappier modelers out there by replacing the cab sims.

You're welcome.

I have tried all of that HG. I even had a Palmer at one stage. Ends up sound much like sims to me tbh. I am quite happy with guitar rig through pr tool for practice, but i drift into the same problem as with pods; i.e., sloppy playing due to lack of clarity. I am keen to practice with a real amp and no effects. I am about to go to K'Rd RS to look at some 1 watt combos with cash in my wallet. Warranty is appealing, even though the prices are not. Doubt they will sell me anything tbh because i am sootying (NZG speak for indecision). There is a LP standard faded onTM i am very fond of and could muster funds for if i flick a bunch of stuff. I dunno
