Seems fishy, guy from Hong Kong upset that his SVT is made in China???

because i just change the caps for my guitar amp, and stomp box. but i really don't know what happen after change it to SVT VR. as the void warranty problem. it doesn't matter. because of some reason, but i don't want to discuss this here.

and my friend decide to mod the caps later. so i will update what happen after i do it. and if he don't like the new caps, i can do backward.

i just do more research of Nover caps. some people say this cap look like UK cap, but it is china made caps. it is not very good.

in fact, do anyone know SVT VR is made in USA or china? because parts , transformer, speaker also made in china. in fact, i think product made in china is fine, if QC and parts are good , it is no problem , iphone also made in china.

hi punkrocko,

if you used to live in hong kong, you will know hong kong and china are big different. even i am chinese, i will say something truth only. china made caps , transformer , tube and speaker is not good. i believe everyone agree with me. but china offer very very cheap labor. my friend (HiFi guy) tell me china handwire Hifi amp just $800-$1200 USD only. lot of us people buy it and change the caps. it is sound good.

kwm488 · #25 05-02-2012, 11:21 PM

and i list some example.

here is the china auction for the 5F1 chasis . it is $25USD

5F1

and here is tubedepot 5F1 chasis, $75.

Tweed Champ Style Chassis 5E1/5F1

if i buy chassis, i will buy from china, because chassis will not affact the tone.

Best Troll Ever.
Anyone know if they make a class D retrofit for my ACC 371???

kwm488 · #27 05-02-2012, 11:43 PM

hi
what is acc 371? is it vox?

but i don't think anyone made vox chassis

Downunderwonder · #28 05-02-2012, 11:48 PM

There was another thread about upgrading the CL transformers to Heyerborg, (spelling?). Was that a troll thread? It had a few guys looking to see what they can sell to get it done. Wanting "better than the original" is not always a slight on the original.

It's a joke, he doesn't want class D for a classic tube amp in a month of sundays.

"Tweed Champ Style Chassis 5E1/5F1"

What does this have to do with anything?

I was referring to this thread as the Best Troll Ever.

And the ACC 371 is DEFINITELY solid state.

as the transformer, i know hammond , Heyboer and mercury is famous. but i just try mercury only . it upgrade my guitar amp tone all the ways. and mercury tell me the worst case is that their transformer quality same with vintage old transformer .

but my friend will not change his transformer for his ampeg, not worth.

for me, i want to get more better tone only, even it sound not like the vintage amp.

this is my recently build marshall plexi. i use Mercury power and output trasformer

they were 'Heyboer'. i've used their trannys in a few of my scratchbuilds and there are great transformers. i had them custom wind them for me for more voltage/power than their standard ones and they are an excellent company to deal with. that said, IMO, the VR doesn't need 'upgraded' trannys. the stock ones sound great the way that they are (at least they do in mine). every vintage 1969-1978 SVT that i've serviced and brought back to factory specs in the last 5 years hasn't sound any better than my stock '07 VR w/NOS tubes in the front end.

hi Johnk 10
thank you to let me know this very important information.
sorry to ask again. are you sure my friend 2012 SVT VR is heyboer transformer? btw, heyboer made in where? but it doesn't matter.

so will you suggest to change the caps and diode ?

the stock transformers are NOT Heyboer's. Heyboer's are made in USA and the stock ones are probably made in China. there was a memeber of talkbass that replaced his VR's output transformer with a Heyboer, but i personally wouldn't.

i've been an amp tech for 40 years and i wouldn't recommend replacing anything in it (unless it is broken/malfunctioning). have you listened to the amp? or do you just want to replace parts for the heck of it?

One Drop · #37 05-03-2012, 01:34 AM

Leave it the way it is until it needs a cap job.

You don't know about bass amps, and just want to make changes based on research but not on how it sounds. Tell your friend to enjoy his amp and stop making him feel bad for problems his amp does not have.

Or sell it and buy a vintage one from overseas if it bothers you it is not identical.

Alex1984 · #38 05-03-2012, 02:13 AM

Owning a VR and a Blackline SVT, I can say they pretty much sound the same. I think your friend's amp is probably made in China, but it doesn't mean that it's inherently inferior. As long as the parts are working, I don't see a need to replace them.

I don't think the OP's a troll, and there's really nothing in this thread that would suggest this.

BillMason · #39 05-03-2012, 02:54 AM

Don't know why people are suggesting the OP is trolling, but consider backing away from your cultural assumptions when you use the Internet, the rest of the world doesn't necessarily have a local version of the "Buy USA" mantra; and Hong Kong is definitely different from China. Kind of like how you speak English but you're not from England.

OP, your English is far better than my Cantonese or Mandarin, (and better than that of some English native speakers, who make up words like "mine's") but please persuade your friend to not change this amp. He perhaps should just learn how to use the EQ on it instead. Volume goes to ten, everything else points straight up, plug in, and play.

jplumansoc · #40 05-03-2012, 03:12 AM

ah yes, Loud Technologies and their wisdom decided to move manufacturing to China. Only if they brought all the same parts with them.

goodluck replacing parts. I would have probably looked on the used market... you could have probably found one with the parts you wanted in it originally for less than a new price.
