Sony TA-F220 - Integrated Amplifier

I have seen several of these over the last years, pretty decent amp with a nice sound. They all have some regular aging flaws in common, though. First, download the service manual. It is freely available from eserviceinfo. The manual contains explosion drawings and some more hints can be found printed onto the solder side of the preamp PCB. As always, sufficient knowledge is implied.

Remember to keep your fingers in the right places and the device unplugged while working. There are many open line voltage contacts near the fuse that can be easily touched by accident.

Amp turns off completely when reaching higher levels, sporadic, DC relay clicks off. This is a fault that can be found by sight. Looking into the case Fig. Logical analysis of the schematic also helps to identify this part, I found it this way even before I noticed the dirty PCB. When shorting the pin 2 , no shutdown occured. On the contrary, I could not measure DC at the outputs before relay while in shutdown, but some DC-ish signal at the protector input.

The reason is the following:. In this case, it is connected in parallel to the input of the protector IC and works as a lowpass filter together with the series resistances in the sensing lines several K-ohms. If the cap becomes defective — which is usually a creeping process for electrolytics — its low impedance region will begin at higher and higher frequencies the more it degrades.

This increases the filter edge frequency, letting more and more low-freq. In consequence, low frequencies of sufficient level in the audio signal will trip the DC protector. The error will grow more and more pronounced with continuing deterioration of the cap. In the case of the F, the original part seems to be a bit underrated in terms of voltage only 6. Oh, and clean the board if the cap leaked. A Q-tip soaked with a mixture of water and alcohol is a good choice for cleaning electrolytic fluids.

The mess needs to be removed as the electrolytic sometimes shows corrosive behaviour. You can see the effect in the next picture below Fig. Dirty relay contacts. The contacts are usually silver-plated to enhance their contacting ability.

Unfortunately, this has the big downside of being a good medium to oxidize. The durable solution is to replace the relay. You can barely make out the different marking in the top left of the following picture. The usual problems with old amps: Consumer products almost always develop bad solder joints. Also check the underside of the main PCB by sight, but usually this is ok.

Check any parts that appear heavy and might move a lot when the case is handled, heatsinks, voltage regulators, large resistors, connectors.

If in doubt, reflow the solder with some flux. The other part are the switches. These are also silver plated, and they develop hard oxides. This can be done by carefully uncrimping the metal tabs keeping them together and taking them apart while memorizing! Then the contacts are closed and re-crimped again. I admit that this is more for the mechanically gifted, but it can be done. Unfortunately, I forgot to take pictures. Yikes, not going to redo that. The volume and tone control pots are mostly not to blame for this.

The quality is decent even if they are not dust-proof. If a mild crackle is present, turn the knob over the crackling section very fast times and it will eventually smooth out. Potentiometers can generally also be disassembled and cleaned, but you risk destroying a part for which you might not get spares. Also, cleaning has rarely kept the problem out for long. Another hint towards the end: When loosely placing the main PCB into the case for testing, always insert the center screw that makes contact to the central ground metal ring contact.

The amp will not turn on if this is disconnected ;-. In this case, that was all. On another occasion, I worked the sister model of the F, the F, which was completely dead. They are pretty well hidden and the F does not have them. Sometimes they will simply blow, probably because of insufficient airflow.

Just take care that you replace them by suitable spares! Fusible resistors are special types that will specifically open on fail, and will not produce a flame. Many producers still make them, but they are mostly only available at Farnell, Digikey, etc. Hi Mario, thanks for the interesting read. I have a F When I first bought it second hand 7 years ago it worked pretty well, then the B speakers stopped working, then A started failing and I would have to turn the input selector quickly for the sound to come back.

Do you have any idea of what might be at fault in my amp from this description? I have opened it and I cannot identify any leaky capacitors. My plan is to change the relay, then check for bad solders, but I wonder if there is something else I should absolutely check.

Hi Clara, from the gradual failure, that sounds like contact oxidation. Might be necessary to use some technical spray. Do not skip the solder joint check though, a bad solder can behave like an oxidized contact well, it is…. I had such a case a few weeks ago where a part unsoldered itself but stayed in place, and would occasionally work fine and then not at all the next minute. If you feel that the problem becomes significantly less annoying for a while after you turn the selector several times, then it could also be the selector contacts.

Before disassembling these, you can try to get some spray into the mechanics and work the switch for a while. Hi Mario, i changed the relay of amply TA-F Do you have some advice for resolve the fix? Thanks in advance. Hi, Got an F and the problem is the receiver turn immediately off when its powered on. I saw two capacitors that may be leaked. Can be them be my problem? What shoul i look into? Should i clean the relay or replace it? In that case assuming all main voltages are present according to the service manual either the output carries a DC offset or it is overloaded.

Since the latter is probably not the case, you should check the DC offset of both amp channels before the relay contact. If there is an offset, the most likely cause would be a blown power transistor in the corresponding channel.

The nasty part is that the protect circuit not only disconnects the speakers, but also disables the front panel LEDs even though the circuit is still powered, so you have to check inside. Edit: You also might want to check all the fusible resistors, like R or R, which might be installed depending on your version. Fantastic blog! I just recently pulled out my old boyhood stereo rack from the attic and remembered why I put it there in the first place — the relay of my Sony TA-F amp was clicking away, spoiling any joy after minutes….

Then after looking for repair tutorials online, I stumbled over your detailed and descriptive blog, which gave me the confidence to think that I can fix this myself even with my minuscule soldering skills! The next challenge is to find a suitable relay and was wondering if I could ask if you think the Omron mentioned in the following link could be a good match? Hi Bjarke, of course you may! The speaker selector switch was the much more troubling part due to the heavily oxidised silvering.

Much more uncomplicated compared to desoldering wick on large contacts. Please, can you explain in detail how to clean the relay? How can I unblocked the cap of the relay? Gianfranco di simone gdisimone gransolarghella. Hi, sorry for the late answer, I was away. Unfortunately I do not have detailed photos of the relay left. If I remember correctly, the relay has a cover part which is wider than the base and slides over. It is then held by two latch pins on the longer sides of the case.

To open it, you have to push from both smaller sides such that the wider sides bend outward. If you force it towards one of the longer sides at the same time, one of the two hooks should come off and you can carefully remove the cover completely. Hope that helps! For cleaning, I use a piece of stiff paper which easily fits between the contacts. I then slide it in and lightly push the contacts against it while sliding the paper back and forth.

Nemo nemorinus. This vintage analog integrated amp has an enjoyable sound, but for some reason the right speaker channel doesn't work all the time. Weird thing is, when I put pressure on the capacitators on the circuit board, slightly bending the circuit board, it usually works again…. Also sliding the volume control on the front panel to maximum for a brief moment sometimes does the trick. I tried bending this part red circle in pictures , which is crooked. I'm nog sure if it's supposed to be crooked. Also thought it was maybe this thing green circle , unsoldered and resoldered that, but to no avail.
