They make the TTA/C004's - very good VAS devices. All my newer SMD designs (HN1Bxxxx series) , very good price and
matched pairs for the duals. Even the P/N matched pairs are spot on.
Sankens are my OP fav's . I even use the sanken OPs' as driver for monster EF3 OPS's. 40-50Mhz ft + 250p Cob.
I don't think I have EVER seen a blown pair of the Sanken.
OS
I’ve seen too many of them. Single pairs of MT200’s on +/-70V, or anything equally STUPID will do that. Yeah, they are strong. But junk receiver manufacturers expect MIRACLES.
Yeah , those olde Japanese receivers, MT-200 + 70V + 4R party speakers (or 2 pair) = Poof ! 3 pair MT-200's @ +/-70V on a Wolverine is
spectacular ! 3pair @ 55V rails is almost impossible to fry.

Has anyone measured this thing’s supply voltage? My guess says it’s 40-ish rails. Can’t read what it says on the caps.
Thank you all for the comments. Interesting. If I can sum it up so far would I be correct in saying the design is a/outdated mostly because of the output devices which may become unobtainable and are rather slow, b/ is 'under sinked' (depending on rail voltage which can't be ascertained from the pictures), the transformer is too close to sensitive circuit c/it uses decent switch gear.
If memory serves well, the amplifier has a big, bold 'out of speaker' sound with average definition and perhaps below average focus. This extended to bass (but was probably held in check by the IB design speakers I've used at the time). Perhaps that makes sense from the points mentioned in this thread. I loved the slim line look and face plate of the amplifier but from the comments but also realise that is probably not a good solution because of the limited heat sinking though I never had known issues whilst using it, even at fairly elevated levels.
Again, thank you all.
I have more amplifiers I would like to discuss/hear your opinions if that is ok. One is an Audio Innovations 500 valve amplifier which I have also owned (and liked) in the past and which is perhaps another contender for re-purchasing. The others are amplifiers I currently own and would also appreciate your opinions and any possibilities to perhaps modify to a lesser extent, which I could do myself.
Would it be better to start a new thread for each one or should I continue in this one?

The past is long gone. You live today and hopefully also tomorrow. Maybe it is a good idea to look in the now.
In audio one meets many that think they can relive the past but even if material stuff of then is obtained today it will not give the same emotions. It can be a rewarding new impulse to find todays pearls and experience todays personal thrills and emotions that come with it.

Hi JP, thank you (and I agree, I have 3 more contemporary amplifiers). Perhaps I won't think as much of the amplifier once I hear it again and, after the feedback made, I am a little more hesitant. Perhaps I want to re-live the past a little bit 🙂.
I will post a similar question about a tube amplifier, the Audio Innovation, in that particular section.
The comparisons of old and new stuff I attended or did myself were rarely in favor of the old stuff.
100% score with sources but exceptions with some amplifiers.
If one decouples emotion from cold facts that is 🙂 A very strong fact that can not be ignored is longevity and mechanical sturdyness of classic stuff. Metal, no plastic. If one desires that then DIY or labour intensive and expensive full renovation of classic stuff is the way to go.
My approach is to design sturdy metal stuff myself but preferably with todays picked out useful features. To pick out chinese pearls and modify those. Today many cheap devices outperform classic stuff. That is when one does not listen with the eyes.

Jethro Tull, Living in the past. There is nothing wrong with living in the past. It is the past and nostalgia that brings you back the good memories you experienced in your audio/music life. It often happens that you still listen to the music you grew up with. Now are you going to spoil your memories with a modern clean, distortion free amp, why it may just not be what you want. It may just show up characteristic that is totally disliked and the music becomes uninteresting. I wish I could have my old Pioneer SA9100 of 1972 back, just the look and feel of it........ Maybe it sounds crap now, but I surely enjoyed it then.
I would also like my old Bentley back. I can never afford it now. The X5 is not even a close second. I still wear my 48 year Rolex and it never stopped, is still waterproof to 4000 ft. keeps time perfectly, and even 10 x more valuable that the day I bought it. Everyone that knows still notice it, take it away and I will kill who try. my wife of 47 years was a miss world finalist, yes older now but still turn heads at her age and I remain as proud of her achievement today as ever. I have never considered replacing her with a new one. We love cognac prefer the aged more mellow ones, nothing fresh to replace it. But we live within our means, don't spend money just for the sake of spending, hence I don't need some ones used SA9100. But if offered new I will buy it today.

Glad not to have the material stuff of then now and when I recently met my girlfriend of then I also had no regrets whatsoever 🙂
Good for you. I hope your girlfriend remains your girlfriend for years. It would seem your previous one did not like you after a while. I must also admit, it could be sh!t to be poor. They say money does not make happiness, but I have yet to meet a poor happy person. All they do is complain how lucky everyone else is.
It IS $#1+ to be poor. Been there done that bought the T shirt. Even if you’re not jealous of the whole world it’s hard to find a way to be happy at all when the places you go and the things that you do are limited to a shared apartment, work, and the grocery store. And anything you might actually try to DO in that shared space are always bothering somebody else. It gets to the point where you don’t even want to get out of bed in the morning.
No need to hit under the belt, person who lives in the past. I also do not understand the sudden made up connection/suggestion with poverty. No man with real character needs to do such nor does he even wants to try to become personal.
Poverty of mind and material emptyness are the worst combination.

I understand you fully and feel your pain. But that does not help, nothing actually helps So I am so sorry I mentioned it, it was cruel and unnecessary and uncalled for., Only if poverty can be outlawed. My deepest apology wg_ski
Well, I am reasonably poor probably because I do the things I like to do 🙂
I'd still like to know if the designer of the amp made provisions for easy repair. As someone who designs and builds things for a living, I'm always curious of how things are built and how they can be repaired if need be.
Looks like the heatsink is on top of the circuit board and there are two large diameter cables threaded though it, there may need to be a lot of disassembly to simply repair it unless there is an access panel under the circuit board.
