Geez.. shouldn't have spray painted the knob...looks wierd if you ask me, nevertheless your preference lah.
I've got my own 2k paint spray gun and compressor and maybe economical if spraying many items but its bloody hazardous to the lungs and spraying 1 or 2 small items including all that trouble may not make economical sense.
The paint costs some RM30 for half litre from a specialized auto paint shop and the special thinner is another RM25. Go do the maths.
A well equipped motorbike shop does offer spray painting, AFAIK. They respray custom colors for owner's bike visible painted components.

The original color of the knob is silver..Adding some color (maybe red) to the knob as an indicator might do the trick...i agree with you..ownself spray paint is hazardous and time consuming and need expertise to make sure the finishing is nice..i think if pass to ppl to do the job is better and faster..

Allu Alloy?

It's slightly cheaper than the Hammond Equivalent. Boleh consider.

How commercial? Maybe spray painted logo/words using templates. Perhaps cheaper than regular laser etching?

Yeah..allu aloy..I have tried using templates to spary wordings for my DIY project last time..result weren't that good cry.gif

Hi guys, Gong Xi Fa Cai..been busy with my newborn baby and now only finish 90% of my T-amp in a proper casing..attached is the picture (taken with camera phone, not so clear). It is spray painted in champion white (that is the color code I was told) as my friend do not have the pearl white which I initially planned for. I've not touch up the power button yet.. For the blue LED at volume knob, its a bit too dim, maybe have to get a brighter blue LED as I thought the low brightness type is sufficient...

Try look for "ARROW" brand spray paint, got the Metallic Pearl White, just not sure will it bond well on Alu Aloy surface.
About the vol knob LED, the difficult part is to get an "even" look of the brightness as the LED is hiding behind hmm.gif hmm.gif

The casing is not hard work..the hard work now is the power switch..to touch up a black color switch to white with brush. I have tried spray but doesn't work as the side of the rocking switch is too tight and scrape the paint out..i have not tried cage type smps yet..the smps adaptor should be sufficient as it is rated 5.2Amp.
As for the tube amp, its from ebay tongue.gif . Bought it after reading some comment from DiyAudio forum and have not start tweaking yet..At the moment, T-Amp is use to drive Epos M5 and source is the ol' trusty Marantz CD63 (modded) & Arcam BB DAC.

I will just stick to the present color as I might spoil the case if I respray. I was looking for a light diffuser/guide that fits that diameter of the volume knob but so far no luck. The only choice now is to use brighter LED and maybe add few more piece of LED..

How many LEDs did you used? Two? Guess you're gonna add another two, right?
I am thinking how to get the LED light to be distributed equally around the pot knob..

hi guys

i am using 3A regulated ic power supply. sound not bad. just wondering if the meanwell smps going to be better investment? found in ebay sell for usd$39 for 12v 12A. bit overkill. just wondering how much you got this locally?

there is "Rayed" brand, for only usd $17 for the 5A. just wondering if you guys have any experience on this? thx

A higher PSU for any amplifier is seldom an "overkill". It matters most of how clean the DC output which noise, ripple and stability which are undesirable. Well design amps are bulky and heavy because of the weight of transformer and PSU. Surely they don't do this for fun. They could have put in any old SMPS PSU if they didn't care. SMPS is mostly meant for industrial applications and of course a cheap alternative for audio DIY'er. 3 Amps PSU is bare minimum.

milen, why do you need 2xSMPS(12V), when you can get a 24V SMPS?

jazzy939, i need +24v 0v -24v for gc. just wanna play around. if the meanwell smps cant disconnect the output ground from the earth input, the 2 smps cant be joined to get the negative voltage. i am planning to get 2 smps with 24 v for GC (which still in consideration) and 1 smps with 12v for t-amp.

any experience with the "Reyed" smps? only cost half of the main well..

Meanwell have dual output SMPS to cater for this, although I do not know how much it's gonna cost! tongue.gif

I have not seen/used 'REYED' SMPS.. have not seen it locally anyway. Half price? Really?

So many types of SMPS can be found at Pasar Rd shops at affordable prices. Just a matter whether reliable or not. SMPS or any switch mode PSU are most prone to breakdown compared to traditional tranny types. Like your PC PSU lah.. all switching PSU's.
