My Diezel Hagen Problem Whistle and noise !!! -solved-

[alexdreamx]

Hello,

My Diezel Hagen produces whistle on all channels.

Apparently lamps which concern preamp V1 to V6.

But that because I have tested and I think V1 (Ruby) microphonic, V2 (Ruby) microphonic and V5 microphonic (Tad Selected) problem also.

Thank you for helping me.

Mister Peter Diezel if you hear me?

Thank you Peter for the fastly,

What is the hum adjust?

My hagen have tubes stock and i haven't change tubes :

V1: Ruby Tubes 12AX7AC5 HG+ 678 Diezel selection
V2: Ruby Tubes 12AX7AC5 HG+
V3, V4, V5, V6: TAD Selected 12ax7a-c
Power tubes: RUBY EL34BG

I buy Hagen in music productiv .fr online august 2011 and my Diezel is Number serial 000/028

Your hum trim pot is in the right setting.
You have a bad preamp tube. Please replace
V1 first.

Also knock on the power tubes, they can cause
also noise.

Thanks,
Peter

I handed:

V1 Ruby stock 678,
V2 JJ,
V3 tungsol
v4 JJ,
V5 TAD Selected stock
V6 Sovtek lp.

The problem disappeared.

I imagine that several tad selected are microphonic because i have not a lost a power loss or gain, however I think I have a fault contact on the socket V1.

For power tubes I type but ras, apparently they are good.

Excuse me for my english approximative.

But I like the sound of the stock tubes

 

[alexdreamx]

I have a fault contact on socket V1 anyway since the tube lights in half if it is believed to have put so much more than her and so I did more than the sound?

Yet the welds are OK on socket V1 underneath.

I have to buy and wait the tubes a one (TAD RT030 TUBE ECC83 HG7025), one tube (TAD RT080 7025 WA) and two (TAD RT001 TUBE ECC83;12AX7A-C)

If I place my new tubes on my Hagen ,it's correct or not?

V1 TAD RT030 TUBE ECC83 HG7025
V2 TAD RT080 7025 WA
V3 TAD RT001 TUBE ECC83;12AX7A-C
V4 TAD RT001 TUBE ECC83;12AX7A-C
V5 TAD RT001 TUBE ECC83;12AX7A-C (Selected stock)
V6 Sovteck LP

Ruby tubes are the best pre/power tubes hands down. I don't understand why folks mix tubes - it must be an anal disease.

 

[alexdreamx]

I changed the tubes out of obligation, it does not amuse me too much change except that the tubes I had a problem cited in the video.

Otherwise the Hagen was fine with the stock tubes.

I'd say it is because everyone has different ears.

I use the Diezel ruby's as well, but some people like different things

 

[alexdreamx]

I still have problems.

I noticed that the pin sockets if the Preamp tubes are too long ago a fault contact.

Diezel do not like mixing tubes.My head Hagen and not Peter ;-)

I have at least two power tubes that do not work as well.

Resolved in December 2011 issue that just came tubes,replacement by pro technician.

Thank you very much.
