Tube Amp Archive

Interesting! Thanks I'll try to know more about this one.
But a 100W first stage is probably not necessary, unless a 4 valves pushpull provides more overdrive than a 2 valves one, which I suspect being the case.

I know my english is not perfect, but it seems rather simple to catch. With a reverb stage before an overdriven power section, dry part will be overdriven, wet part not entirely depending on the decreasing swing level, thus providing a mismatch between dry and wet sound. It is like putting a delay b...

experts,

This might be a stupid one (I suspect so...), but why do we design amps with Voltage gain stage, then Current raise stage and not the other way around? At the end, we will have wattage the same way, isn't it?

I see. But for sound consistency, wet part should also be the overdriven one, not a mix with the clean. It could be interesting to design such an amp, by capturing a part of the output, apply the reverb, new push pull and final mix with the dry before the output transformer. Heavy design but probabl...

@joeCon

Yep, this is what I meant! The (clean) reverb sound will probably be awful and for sure iregularely overdriven by the power tubes.

Hi!

For a high dynamic bluesy sound, a design that saturates output tubes easier than preamp is often advised. How can it be so as the reverb stands before the power section?

Thx

Guys, In Europe where I am living in, wall plugs deliver 220V AC. Let's say I wanna go for a 25W amp design - considering the price of transformers, is there any reason for not going for a power tranformerless option? Should be enough for2 pushpull output tubes, 1 rectifier, 2 preamp ones and 1 reve...

Phil_S Thanks for the time spent on answering! I got all your points and I highly agree with this. I play blues guitar since almost 20 years now, I obviously know what's the part of the player's technique in sound's shaping. On the practical side, I also know that every art takes time to learn and t...

Hi all, After having read 4 or 5 of some good books and having now a pretty consistent understanding of overall amps technologies, I am wondering where/how I could learn which design to go for if I want to achieve such or such tone - some guidelines in fact. Books describe each stage with a very gre...

Samamp discontinues its amp production. Too bad/

Does anyone have a schematic of VAC 23 model? Its class A and typical dirty blues sound would be very intersting to study!

thanks guys

Thanks mates!

I've downloaded both. I will surely give some feedback soon.

Hi guys! What's your approach for designing an amplifier? Does anyone uses a schematic software which can simulates current/voltage values? If so, anyone to recommend? I know that components'final values are to be adjusted once the amplifier up and running but we need something to start with, don't ...

Super!

Great link John! Thank you very much

Hi experts!

Is there any link listing all common valves with power, dissipation.... and equivalents US/EUR? For instance, I am looking for the EU equivalent of a 6JN6.

Thanks in advance.
