junchoon, I have learnt through many expensive mistakes that `easy' is a very deceptive term. What's easy for a sifu is not easy for Butterfingered Joes like me. In my hands, an `Easy' job can rapidly turn into `Messy' job.

That's why one must treasure the sifus when one can find them!

Hey, I just noticed your invitation for a TT session tomorrow....anyone taking it up?

Morning guys, I should be able to join but unfortunately only for a hour or so. Too many weekend home chores left uncompleted lah.

Jazzy bro, I no can give technical support, so at least must contribute moral support lah.

The volume pot is an eye opener....finally I'm hearing my T-amps without colouration from the Yulong DAH1! Only drawback is the output from the CA640P is too low....so it looks like I have to add in an active preamp somehow. Maybe time to invest a tube based preamp.....

junchoon, okay got your directions already. see you later!

Me don't have lah, but we know bsl555 will have one stashed somewhere, somehow.

jazzy bro, you're treading on thin ice!

Y.C. that was a neat compliment on the HB2s. Gracias, bro.

I will continue matching them up with my current TA2022 as I feel this combo delivers a slightly punchier and beefier bass compared to the TA2024, although the pairing does seem to lose out in fine mid range texture. Overall, this appears to be a better balance/compromise to my ears. But I most likely will be picking up a TA2024 to be used as a general purpose portable amp and it should be interesting to do a prolonged A-B between the two T-amps when I have the time.

What ho! A real veteran! We should start a Senior Citizens T-amp club.

But Jazz bro, why no nakid pics? That buffer pre-amp box could be empty for all we know....

Oh Jazzy bro, you're right! It really looks er...bare.

Okay, okay, I know lah. You like plenty of room to work in. And enough space for future addons. Like that active X-over, perhaps?

Yippee, I'll be getting my very own TA2024 to play with tomorrow .

Oh my, I've already pumped in nearly RM1K for my TA2022s and the recently acquired TA2024s. And I haven't even started an modding yet! Wonder how much more I'll be putting in for the cases and the peripherals like RCA sockets, volume pots, switches, etc. Exciting, ain't it?

jazzy bro, my TA2022s're still mounted on a piece of ceramic tile...and I reckon I won't change a thing until I come across a nice casing I really, really like (which may never happen. BTW I have seen one strong contender - yours!). Of the 2 new TA2024s I have acquired, I don't think I will do any mods (yet). One piece will be turned into a general purpose portable amp to carry around everywhere. The other will likely go into my much abused utility 4WD vehicle (finally, an `upmarket' sound in my car on those midnight stargazing trips to the middle of nowhere).

Don't worry, Y.C.. I've caught the bug. Only not so serious lah. I will, sooner or later, do some mods. But I'll only do it once - the more times I try it, the more the chance I'll screw up. So I've got to first decide on the exact caps I'm going for, buy or steal them, and then it's time to heat up that rather lonely soldering iron.....

BTW, I think xtorm is considering moving this to version 2 soon as it is now much too long for newbies to read and comprehend. So the LYN T-amp club will still live on.

Both, I reckon. I may occasionally hook it up with the Yulong DAH1 `cause sometimes I'll be using the USB input from PC based sources, and when I'm spinning the turntable, I need the slight boost due to the low output from the CA640P (at least until bsl555 fixes that problem for me). And there's also the convenience of the wireless remote in using the Yulong. I'm a true couch potato.

But when I'm playing with my CDP I can get by with just a passive controller, so I'll have a volume pot added in at some point in time. At the moment, your passive preamp is doing the job extremely well with the TA2022s.

As for doing a buffer preamp...I think that's going a bit too far for my DIY capabilities.

Is it general consensus that the Vishay 2.2uF is at the top of the list as replacement for the input caps?

Guys, I guess I can understand a bit of Dybre's confusion. This thread is too long! Even for me, it's hard going back through the 130 pages to pick up the relevant points. I'm eagerly waiting for xtorm to move to V2, with a nice summary of all the important stuff as the first thread.

Looks like we may even delve into which car battery drives the T-amp better! It has been my intention all along to drive my T-amp off batteries ....anyway, I use batteries extensively to keep some equipment isolated from the unreliable mains. Because I want to stay portable with the TA2024, this is also a natural path for me to take (KISS!).

Perhaps at the next TT session, we can do a comparison, eh?

jazzy bro, I have this unerring inkling sooner or later, I will.

But I think I'm getting an overdose of equipment at the moment....new T-amps, passive preamp, the newly modded CA640P with ultra-beefed up PSU (thanks to bsl555), my HB2 is back in the system (but one tweeter is definitely in the pits, it's ringing like hell), and I'm still finetuning the GyroDec.....my heart can't take it anymore. Not to mention, the Philips SHE9850 IEM is now settling quite nicely and pulling me totally in a different direction - IEMs are so antisocial, right?

Anyway, I will do a bit of comparing between a 7 aH SLA battery and a 60 aH SLA car battery with the TA2024 in stock form first, since these are at hand.

bsl, my next trip to your place, I'll pick them up pronto. I've got various assortments of 12 volt DC fused/unfused cables in hand, including those thick stiff battery to battery transfer ones...we'll see if cables make a difference too!

gabanyayaya, I wish I had your resolute resistance to this involvement.

Y.C., now I understand why you don't go for battery power. Yalah, quite inconvenient in this case, to have to shut down and disconnect the battery for charging every few hours or so.

wui, do you get the thump if you turn the volume down to minimum, wait about 15-30 seconds and then power down the T-amp?

Y.C., for the sake of discussion, a capacitor primarily functions as a on-off energy storage device, i.e. it is constantly charging and discharging while you are using the amp. So how much difference would it make if you manually power it on and off a few times a day compared to the billions of times it's doing that in its lifetime? I would think that leaving it on all the time (and thus keeping it heated up) would be a bigger drawback to its lifespan as constant heat would contribute significantly to the fatigue of the internal components of a capacitor.

Of course, any unusual condition involving overvoltages and sudden temperature changes can cause premature death of a capacitor. But isn't it heat (over a long period of time) that ultimately reduces the normal lifespan of any electrical/electronic component?

BTW my 25" Sony TV has gone two decades without a single failure of any of the capacitors. But it has failed a couple of times due to solder fatigue...and one case of a push-button power switch failure. Current problem...thanks for your strong hint, bsl555, seems to be one obscure wirewound resistor which has somehow increased its resistance. Oh no, I'm not dumping it yet.
