Re: Classic 60

Yes Admin, and the look of the transformer wires, due to the short, looked kind of a smoked color. My bad guess. It was just that. And also the great tip from Jeff. Using a variac is the way to trouble shoot vacuum tubes...or shorts of any electronic component. The amps reading meter built into the ...

Classic 60

Hola Chicos, Just got from a dear friend for repair a Classic 60 power amp. The unit did not turn on. So the first thing that I did was to check the power fuse that it is located at the IEC power cord female connector. The fuse was totally smoked. Then I opened the bottom of the unit and my bad gues...

This is the huge Lampizador Big Seven that I was listening in my system...the overall sound is high quality too. The tubes were removed for transportation.

Re: Oh! For the love of tubes!

Hola Chicos, One of my best friends and a crazy audiophile just passed. His system was more like mine, having him all kinds of electronics around too. There were Pass Labs preamp XP-12 and a XA-30.8 power amp. This is a 35 Watts power amp with a real weight of 88 pounds. More weight than my Classic ...

Re: Premier 17ls pre amp tube question

I used in my ET-7 model preamp the Holland made Philips E88CC, with a very happy sound, but I had a noisy channel, I did change for a new E88CC and got another noisy channel again. Then I tried the Genalex Gold Lion 6922 and the overall sound was not as good as the Philips, mostly regarding the harm...

Re: Channel Imbalance, CT5 easy fix

Good advice and also a very good point Admin. Cheap batteries might leak and ruin the remote control. That happened to me too. Good brand and well known brands are almost leak free. This does not means that the expensive batteries do not leak. And yes, they do. Your advice must be done every two mon...

Re: Channel Imbalance, CT5 easy fix

Hola Chicos, I went back to the famous rabbit playing the drums batteries...they last longer than the Amazon batteries. This is my finding and in my system. The price on the Amazon batteries is lower than the Duracell, but I'm sticking with the Duracell. And yes, fool of me. This might be because of...

Re: Electrolytic cap on CJ preamp (PV9/PV9a)

Hola,

Judging by the drawing, and see also bride diodes, this tells me that it belongs to a part of the power supply. Do you have any hum once the unit is on? If you don't, the cap is working fine.

Happy listening!

Hola metaxa64, Welcome. Great to know that you own ML speakers. I have the CLXs model, and I love the way that my Classic One Twenty SE power amp drives them. Because of the low impedance that ML electrostatic has, I do like a lot how the CJ output transformers handles it and drives them. Oh well, t...

Re: replacement of pv7 power supply capacitor

Hola. In a power supply, it is very important to have the voltage value the same or more working voltage . The capacitance, if you use a higher value like 50uF instead 40uF, you can do this, but never lower a capacitance value.

Re: Nordost Heimdall 2 interconnects and power cable

Great advice Admin, Right when twisted cables could make an inductor. If the cable is too long, "S" or snake shape is recommended. I did reverse my speakers amp connection, because the ET-7V2 does has inverted phase. Also, with Audirvana or the HQPlayer, there is an option where I have che...
