regardless of the schematic diagram where the tantalums to be replaced are placed?
Another interesting thing about tantalums is the dissipation factor is decently low, but more importantly, it's very consistent from part to part. Manufacturers like predictability.
Unless you are working in some weird and wonderful circuitry, capacitors above 4µ7 are generally not all that critical, and are usually used for power supply decoupling. For coupling purposes, I have used the UKL (10µFd/25V & 22µFd/25V) in applications up to 100kHz without issue.
If you compare same value/same voltage Tantalum vs UKL you will find that they are virtually identical in tanδ, and the UKL is usually better in DCL (uA).
I took a quick peak at the schematic for the unit. I found some very "interesting" design choices. It seems that many of the Tantalums are being run back-to-back in order to create a non-polarized device. And they are running two 470µFd/3V15 (per channel) in parallel as input blocking caps for the phono stage...
@audio king in your opinion is it a circuit refinement that forces them to be replaced with other tantalum or are the opinions expressed in previous posts valid?
I have a tuner that have a few tantalum caps in the audio signal, the tuner is a Accuphase from 1975, I was told by a few guys which have the same tuner, not to touch the tantalum capacitors.
I am going to replace the tantalum with new ones.
Who makes the best audio tantalum capacitors ?

About these famous tantalums in the signal. I had 3 of this tuners and modded one with black Gates N. to replace the tants. I didn't like the results at all and returned with originals. Peter Daniels renowned on DIYaudio.com did the same constatations with the T-101. If you try to replace them. Take time to do a good broking in time on new caps (about 100 hours) before doing serious listening."
