Any Allnic users out there? Hum problem.


I brought this up previously but was not very specific.

I bought an H3000 phono stage which I liked very much and was perfectly silent. I then bought an HA Head Amp which had a slight hum. Shortly after I got it one of the transistors blew(I believe,) it went dead and I had to return it to Korea for repair.

Since I've gotten it back the hum is worse. When I play a record the sound covers the hum but when it stops the hum can be heard and felt from the speakers where I am sitting about 8 feet away. I asked the maker about this and he told me he sent it back to me in perfect condition so that's a dead end.

Is a hum to be expected? Do you live with it? Is it a grounding problem? I asked the maker about this as well and he did not respond to the query.

I would greatly appreciate any advice from Allnic users and especially those with the HA3000. Do you get a hum? Is it noticeable when an lp isn't playing? Any grounding suggestions?

My amp is a VTL S200 with an Ayre pre K5 xe mp.

VTL super scoutmaster with 3D tonearm.

Conditioner is an Isotek Sigma.

As I said everything is perfectly quiet until I turn on the HA.

I want to fix this because I like the Allnic sound enormously and don't want to be without the HA. It really is wonderful.

Thanks for any thoughts you may have on my situation.

Hi vetterone, glad to ''see'' you back. Whie hum is considered to

be a kind of enigma I was confronted with this problem only

twice: with Glanz MFG 61 and Allaerts MC 2 ''gold finish''.

My enigma is ''why my Lord ?'' with my  best ever MM as well

MC cart???

Dear Lew, You are my English teacher. That is to say that whenever

I don't understand some English expression I ask you for

explanation. However methaphors belong to other kinds of

expressions. I also know that the expression ''Lord'' has no bearer.

To put this in linguistic terms: ''Lord'' is a name without reference.

So ''my Lord'' is a way of speaking. I am really wondering, why the

hell my two best carts have hum problem? I would be much less

disturbed by any other of my 50 carts (grin).

Dear Lew, What do you mean with ''the devil''? Someting like

Pegasus or unicorns? Also what do you mean with ''my languge''?

I have at least 3: Serbo-Croatian, Dutch and German. My modesty

does not allow to mention English and Russian(grin).








Dear Lew, To me those details which you mentioned looks like

variables. You of course know that there are many while each

variabale needs some value to make sense. While I left Serbia

50 years ago I still think that Serbo-Croatian is my ''native language''

Here is an Serbian saying which I like very much: ''you will be sorry

for what you have done and also for what you have not done''.

We all are free to make our choices but, alas, there are so many.

Like ''to many variables'''.

And yes you are right about people divided by the same langauge.

The Serbian and Croats are willing to start a new war in order

to decise which language is older: Serbian or Croatian .

BTW the Serbian don't need any reason to start a war. ''Pure

passion'' so to speak(grin).
