Nikko Solid State Stereo Amplifier - Identity

[mozcho]

There is this amp available in my area, but it only says "Nikko Solid State Stereo Amplifier", no model number is given. If you know the info like model and specs, please let me know, and how's the sound quality. Thanks.

Ad states RM 480, but being a Nikko, I would guess TRM 480. Google shows nothing for that, except the one in question.

If the price was right, I would try it out.

It's been for sale almost 3 years now?

no, the RM is the currency, that is equivalent to USD 120. TRM480 may not exist.

Messaged him but no response, but there is another seller on a different forum with this model too, just some $30 more. I need to know at least the wattage and the schematic for future repair before making the purchase.

TRM-120 - from around 1971, possibly older.
Looks to be pretty rare. I'd grab it if it works. But even then, expect it to need restored.

The seller claims is it TRM120, but a google search doesn't yield any convincing proof except this:

Sadly no photos on the exterior!

Ha ha. I don't get out much.

Update: The seller reports that he saw a very small print at the back stating TRM-120, so this more or less confirms the model number. However, the net is still empty on the specs and service manual/schematics.

[QUOTE = "mozcho, post: 12369169, member: 289000"] El vendedor afirma que es TRM120, pero una búsqueda en Google no ofrece ninguna prueba convincente, excepto esto:

Lamentablemente no hay fotos en el exterior! [/ CITA]


Si hay al seleccionar una te da opción de ver en un tamaño normal.

Todas las demas.

H

De nada.

Si quieres pasame tu correo y te paso detalles de lo que le toco hacer a mi NIKKO TRM120

 

[AJSV]

Thank you bro. Gracias.

Mi equipo al día de hoy no se que le paso mi hermano se lo llevo para una fiesta.

Indico que se apago.

Pero Consultando. O le derramo algo dentro; lo siguieron utilizando y ocasiono que se dañara el pre amplificador para un sonido deficiente con daño en los condensadores principales y otros del pre.

Costo detectar falla por la cantidad de condensadores. aunque me falto revisar dos transistores mas del pre.

Lo bueno es que los transistores de potencia estaban buenos al igual que las resistencias de las salidas y el center ch out put.

Toco hacer un pre acorde a la capacidad de los nuevos condensadores por 4700 uf por 50 wv incrementando la potencia en el mismo.

Condecir que tiene la capacidad de mover:

Cuatro: W8MC BOHEM de 8 OHM de 70 WHATS.

Con cuatro: M5NP de 8 OHM de 40 WHATS.

Con 8 twister

O superior a esos.

¡Adjunto fallas y reemplazo!
