You said it. biggrin.gif Not unless you want to hear a fair bit of added distortion, and risk creaming the Aego m's built in amp and maybe the drivers as well.

That's a nice complete TA2024 and good price too. You're thinking of bringing it in?

After a 6 hour marathon on Sunday, I finally got my TA2024 up and running. Straight forward DIY job on the casing, no caps mod yet, as I want to assess the unit in the stock mode first.

I need to bring up one question which has been asked before....but I still don't understand the answers, sorry folks. blush.gif What is the ideal volume pot range to use with this? I'm currently using a JP alpha 100K log volume pot on it, and I find that I have to crank it to near maximum before the volume is loud enough to my satisfaction. At maximum, the T-amp goes dead, and I have to power it off and on again for it to work. Is this normal?

Y.C., thanks for that link. There is one paragraph there that approximates the question I was trying to ask...:
2. Choose the value to match the input impedance (of what the stepped attenuator will be controlling). This applies to both preamplifiers and power amplifiers when the stepped attenuator is to be installed at the input. If necessary, check your owner's manual to find the the rated input impedance of your unit. Or contact the manufacturer.
Does anyone know what the input impedance of this TA2024 unit is?

I've got both types of the JP 100KΩ volume pot, linear and logarithmic, purchased from Nixie. I'm using the log one, as this seems to give a smoother spread of volume control.

Would using a lower value (as advocated by LittleGhost) than the rated input impedance mean that the maximum volume achieved is higher, and still provide a lower noise threshold? I would think that logically, noise would increase with amplification. Hence my confusion.

xtorm, in spite of everything, you still are very cheerful. That's an admirable attitude! rclxms.gif

I can only offer you this famous phrase `Behind every dark cloud, there's a silver lining.'
