Thinking of assembling a passive preamp but has zero DIY skills. Do you know a specialty shop or somebody doing this? Any idea how much it would cost?
Here's a pic of what I have in mind:

How about locally sir Tony?

no chance, if ever parts will be imported anyway...

From the picture itself, this seems passive attenuator with input selector? I'm not sure if this is Passive Pre-amplifier. But it uses DACT product
Maybe this is the real passive amp:

that's a TVC also a passive preamp....
-
just thinking out loud... isn't it wrong to call it a passive preamp? technically there's no preamplification, just attenuation. sabagay masyadong mahaba yung passive attenuator with input selector. ;D

talaga bang there are no good pots and selector switches available locally?

walang locally available na quality parts........ you have to order them on-line like greyhill rotary switches and peny and guiles conductive plastic pots........

to me these are passive since there are no active devices used in the signal path, meaning no tubes, no ss parts....

Sayang nga eh. Sabi ng kumpare ko he can do something like this but he's not sure if he can get the best parts possible here.

I have one like this but used resistors from alexan, selector/switches from ebay. You can look online for small items may mga free shipping via post office nila padala....

TVC seems have gain....
this one is very expensive passive preamp:

Thanks!
You can contact Mang Rod Teope for your project. I think his number is 5221696. I believe he can source the resistors as well.

if by gain you mean positive gains then yes, it is possible for TVC's to have gains.....isolation types with a 1:1.4 turns ratio for example.....
auto transformer type TVC's otoh have negative gains.....

ganda nga rin ng passive preamp, pure signal from the source to the power amp then to the driver/s
wanted also to try one kaso wala ata available locally unless custom made
and dami variables dapat match sa system yung specs ng preamp
-
glorified volume control....;D
-
haha onga po sir Tony :D
ang mahal sa ebay ng mga passive preamps kapresyo na rin ng active ones kaya mapapaisip ka rin kung willing to pay for it kasi napakasimple lang
sana me ma audition dito
-
naka lineup sa gagawin ko in 2013...tvc...
-
uy, something to look forward to next year
nice!

If this is a TVC passive preamp, why does it have a grounding lug?
