|doobooloo: Please get a schematic of the amp and post it in this thread once you get the kits. I am interested in replacing some of the parts. Also, could you get some case measurements when you get it(internal)? I would like to know how big of parts I can use.|

2. Use pure silver wire where it matters
3. Replace front, rear, and top covers with custom acrylic panels
The reason why I am thinking of #3 is that people have mentioned that the amp gets rather hot during operation. So, I thought that using a ventilated top panel made of acrylic would solve this problem AND show off the tube glow. However, the top panel on the HP-100A is actually the BOTTOM panel, so when this is done the front and rear panels would be upside-down. So, I would need to create custom panels for the front and rear as well...
The thing is, I am not sure how much all these upgrades would mean to the amp. The amp is ~$100, and the upgrades can EASILY go over that. A stepped attenuator can cost upto twice the amp's price, and even replacing the RCA jacks can cost more than the amp depending on what jacks to use. So probably only the really high cost-benefit ratio mods - better film caps and silver internal wiring - will be done.
If you're serious about this option then I can arrange it for you, and of course, do the upgrade according to your specs. For now, you need to purchase the kit version of the amp if you're serious so that I can get the final list of buyers done. I am not sure if I can take two of these heavy kits back home given how much of everything else I also have, so I may have to ship yours to my friend's place in Philly first, build it in September when I return to the US, and then do the mods/build the amp, and ship it to you from Philly. So shipping charges may be incurred twice, but of course shipping from the US will "only" be like $15 bucks by ground.
Let me know if you're still interested!
|thanks doob for this answer ..but wop too much time to wait september ..
ok i'll search around a little bit about his sound sign. then back to you in pm with my interest
|wouldnt acrylic melt?|
