King,

PP output transformer cannot have an air gap whatever wide or narrow, isn't it?

:)

I got a Manley 300B amp can be swtiched from SE and PP to match with different loudspeaker and sonical preference.
--------------------------------------------------

i don't know how they do it. it is a bit tough to have make a transformer for both SE and PP. SE transformer needs a large air gap to avoid saturation. PP transformer does not require that except for non-match tubes so it usually has a small air gap. if a PP transformer has a sizable air gap, the inductance will be significantly reduced hence the low frequency response. so instead of making the amp best of both worlds, it might end up with worst of both worlds^-^

coming back to your question, i think most SE amp designer has high efficiency speaker with nice impedance curve in mind. 3/5A does not fall into that category. but of course one can design a SE that can drive 3/5A but these are not common. may be i should design one^-^

Gingers,

Interested to come for the Coda 7 vs. Coda 8 mini-party this Saturday p.m.?

I would take the opportunity to "poison" comers with your favourite, the LS3/5A, after the 7 & 8 fight.

Baby 12.1 :-)

This one? 心向太陽

WHY not Chinese :-)

Will not be named "PP" or "SE"

Haha.. that is also true to say "there is no such an amp called PP and SE" until my next (don't know when) amp will be called "PP" as its brand name or model number.

no! there is no such an amp called PP and SE. i think the question to ask is whether this amp A is better than the other amp B in driving 3/5A to you?
i think implementation is way more important than typology.

SK Tung,

In this thread I did not find Drwkng said "there is no such an amp called PP and SE".

He did say "mono-bloc has nothing much to do with PP or SE". Indeed monobloc can use SE, PP or other designs.

Cheers!

It seems that PP setting is more suitable for 3/5A. Therefore I would like to know any 3/5A user have the same experience/comment.

Thanks!

Gingers,

I just rcvd a spendor 15 ohm la....

Pye Mozart HF10 is a mono single-ended integrated amp with one single EL34 each.

Pye Mozart HF20 is a stereo single-ended power amp with on EL34 for each channel.

But having 2 output tube for each channel does not necessarily mean the circuit is PP. It can also be Parallel SE or PSE e.g. Jadia 300B monoblock or Unison Simply 4 etc.

Thanks! Understood! : )

From what I understand, the Pye Mozart HF10 is single ended amplifie but with the mono block the Pye Mozart single ended in push pull mode or merely 2 single ended amplifiers?
---------------------------------------------------
i don' know the circuit of HF10 but mono-bloc has nothing much to do with PP or SE. so if it is a se, it just means that. one se amp for one channel.

Hi! Just one question on PPO & SE..

From what I understand, the Pye Mozart HF10 is single ended amplifie but with the mono block the Pye Mozart single ended in push pull mode or merely 2 single ended amplifiers?

Thanks! Sorry for asking such stupid question.. : )

I originally ask this for SKtung because I have no expereince on 3/5A.

generalisation is hazardous to health.^-^

That saying is QUITE true and it is the reason that I say "USUALLY" (but not always).

Will 3/5A sound better in PP than SE?
