HELLO, CAN SOMEONE TELL ME HOW TO ADJUST THE WAY TO NO DAMAGE THE TRANSISTORS
AS IF BEGIN OF 0
ADJUSTABLE RESISTANCE TO HAVE TO BRING THE COUNTER CLOCKWISE GIVING THE MAXIMUM STRENGTH.
ANYONE CAN HELP ME IF I HAVE THE SERVICE MANUAL.
THANKS

COUNTERPOINT NPS-100 BIAS

bias voltage leads to step counterpoint NPS100
has deregulated potentiometers bias and ofset
points where I should measure, and precautions and change
several transistors
thanks

conterpoint NPS-100E help

hello someone would outline the power of counterpoint NPS100E
I can not ask for help adjust the bias. thanks

Hello I have an audio research sp 16 and I want to update changed the transistors
anyone know referenced are the transistors as they come color

What is the issue with it? It is a valve pre amp using 12AX7 (ECC83)!

audio research sp16 phono no rec

Hola al usar la sección de Phono con la salida de grabación conectada en el REC me hace ruido como de realimentacion, solo con el phono, en cualquier otra entrada no y no descubro lo que es y no puedo grabar vinilos.
Aguien me podría ayudar ,gracias

Hello to use the Phono section with record output connected to the REC makes me sound like feedback, only with the phono in any entry not and discover what it is and I can not record vinyl.
Aguiar could help me , thanks

"..makes a noise like feedback,only in phono, not with any other input..." " Could somebody help me please?".

This is an English-language website, as one of the Mods will soon tell you. We can cope with weak English (unless it comes from a native English speaker!), or get a friend to translate for you.

Aguiar could help me, thanks

the REC connector is not the phono input, you must connect record player to phono input.

The rEC connector is an output to a recordind device, such as a tape recorder.

does this help??

I selected the phono and if I rec output connected to the DAT makes me noise with other entries

What is the equipment? When does it work OK? When does it not work?

the transistors of the power supply are not colors and to change the reference

 

[JonSnell Electronic]

The type will be printed on the transistors case.

I would leave the power supply as is, because you may cause unexpected problems
when changing parts. It is a carefully tuned feedback amplifier.

Having worked on older ARC designs I will second that comment. In addition there is nothing to be gained changing semi-conductors in these units... except trouble.

 

[kevinkr]

The type will be printed on the transistors case.

ARC often uses house numbers which are hard to cross to generic commercial types because they don't provide that information.

I think some of these devices are selected/screened for the application.
