If I try anyway, do you still think that maybe the DC offset would be improved? Transistors Bipolar – BJT. I can find these, but I do not know if they’re a good replacement.

This is very educational and fun for me. Unless the amp is running at high voltages, they all should work. However, the DC offset is very high. I tf2955 intend dafasheet get the proper transistors soon, this was just a test.

There seems to be a problem serving the request at this time. BinaryMikeAug 1, I do not really understand how to find comparable devices, so I would really, really appreciate some guidance on this.

Thanks for the advice so far. Buying Format see all. Any help would be really appreciated!

BinaryMikeJul 29, Skip to main content. If we send you the wrong item, obviously we will correct the situation. Thanks a lot for the help!

Oh no, there’s been an error

RuxmanJul 29, Also, a small 1uF cap had exploded on this channel. Please provide a valid price range. HyperionAug 4, That’s enough increase in speed to provoke HF instability in some amp circuits, so the repair definitely should be checked for parasitic oscillation. Receiver Number of Bits 1. I see that 10R series base resistors are used in the output stages, so faster output transistors are unlikely to cause difficulty.

Dynaco used TIP transistors in several of their designs. The original output transistors were TIP34B, and I need replacements but they seem to be impossible to find. If anybody is interested, here’s a schematic of the amp GIF, kB.

Or is this caused by another part in the circuit? Guaranteed by Fri, Jan 4. A total power supply voltage of 88V is really asking too much from anything in the family, even if the devices were pre-tested above that voltage with a curve tracer.

Discussion in ‘ Solid State ‘ started by RuxmanJul 29, Maybe that is why it has been smoked? Some are probably very.

There are no adjustment points for DC offset in this amp. IMO the 2sb and 2sd would probably be the best sounding if you could get the original Toshiba parts – most are now made in China and vary in quality and reliability. A random pair of KSA devices from the catasheet batch are probably matched datashet enough for the input diff-amp stage, especially if you get them from the highest hFE ranks F or E. Guaranteed by Mon, Jan 7. In stock at mouser.

As mentioned, the originals are TIP34B datasheetbut on the blown channel, someone has replaced the transistor with a 2SB datasheet. Man, it is difficult to find these output transistors. Log in or Dtaasheet up. Power Dissipation Max 2.

The KA can operate at power. So I take it that these two transistors are the only thing that is relevant for the dc offset? Now, with your insight, I looked again and found something of great interest! It’s an OEM amp Rds On Max Id, Vgs OK, so the mystery is solved. A recap, for example, won’t help at all?
