If a sound was supposed to be in the center, it sounded like my equipment rack was a speakeri.e., projecting from direct center. The Spendors always had a very good left/right soundstage - not magnificent. Spendors are known for their midrange, tone and accuracy -- being critical of the soundstage is not something even advanced listeners every mentioned in my
Battery Powered Tube Amplifiers. This section contains schematics and description of all battery powered tube amplifiers. The couple watter uses PP or PPP 6AK6 output stage and includes a switching supply to upconvert 12 volts to about 170V.

A few months ago I bought a second hand Audio Note Meishu Line amp. For my more relatively modest means it was an expensive purchase plus the amp had certainly an age.
I replaced it and never fixed the problem. I also replaced the fuse. We have a bad lightening storm and I think it was a power surge that got it.
Part Number: BQ51013B Other Parts Discussed in Thread: BQ51003 Tool/software: The datasheet clearly shows these as 47nF in Figure 8-11. The description states that when the COMM switch closes, there is 22nF between AC1 and AC2, which I assume is derived by the two 47nF in series (not exactly 22nF, but close).
STEVE''S TEST Hello, Christer,here is a partial answer to your QQ: "I measured several different types of parts, and captured the results (simply by training a camera at the scope). The value of each of the capacitors was constant, 0.1uF. The signal level was held constant at about 70 volts RMS at 600 Hz across the capacitors.
I have a dual amp kit in my tahoe. From the battery I have 2 gauge power wire running to the back into a distribution block. (2) 8 gauge power wire going to each amp. 8 gauge ground wire from each amp running to their own seperate ground.

You can play around with the uF a little bit, if you can''t find a 13, find one a little bit higher, may even be a bit cheaper if you get a common value. Rule of thumb generally, is not to go below the uF value, but a little higher is ok.
What caps are in there now? Is there something wrong with them? I would leave it alone unless they need replacing. Sure Jupiters and V-caps are nice sounding caps, in the right circuit, and likely will change the sound but remember the amp was never voiced for those, so they might sound great all the time or in some volume or frequency ranges they may sort of
Make a list of the caps and their values. A good cap chart can help identify things. Then talk to a local electronics shop to get some advice on the best current replacements - there are several different types of cap (of the same values) that will work.

Hi, I am thinking of replacing the capacitors in my crossover. Does it matter if I replace a 5.6uf 250v with a 5.6uf 400, 600 or 630 (v) capacitor?
Digi Key part number 1934-1132-ND for the torroids Fair Rite 5952003801 mix 52. Chose more expensive mix for power handling. About 12$ each including tariff.
3 · The Register asked Brown about the incident and what the future held for the now-repaired LC III. He told us: "My plan for the LC III is to tinker with it." Brown added that he was also teaching himself how to make expansion cards for the LC series of Mac and paid tribute to the enthusiastic members of the vintage Mac community who still come up with ways of
many moons ago, I upgraded the ''crossover'' (actually just a high pass tweeter filter) in my beloved Triangle Titus monitors Triangle 202 tweeter hi-pass upgrade Thinking yeah, I''d like some Ref 3A MM DeCapos, but knowing how much better my Tituses sounded after that modest upgrade, whose capacitor isn''t super highly regarded in Humble''s HomeMade
Results. Mid Oct 2013 . Testing the Coil - Preliminary tests. With all the components done, it was time to test the coil! I was still not done with my actual secondary coil yet, so I used a
Just curious if anyone is aware of a good place to buy high-grade, audiophile replacement Electrolytic capacitors. I had a cap blow today on one of my amps.
Hi all, I have an old NAD 3140 amp. I''ve used it for the last 17 years on a particular room of my house without incident. It''s connected to a pair of A speakers in the room and little B speakers that are on another floor (far away enough that, at first, I worried that the length of the rather thin cables would stress the amp, but never had a problem).
hey gang. I am having difficulty identifying this capacitor and what exactly it''s value is. this is the motor and cap photo from my jukebox, yet I cannot find the value of this cap anywhere online, nor am I able to identify it with my limited knowledge and it''s markings. I even have an esr meter which usually gives a good indication, but when I test this component, it
SETTING UP AND OPERATING THE CIRCUIT: Supply 10VAC - 20VAC (or 14VDC - 30VDC) to the low voltage input (listed as "12V" on the PCB). If you have a scope, measure the signal between the MOSFET gate and source, and ensure the circuit is oscillating.
