Capacitor


Dear friends I am interested to upgrade my caps in the tube preamp from Audio theta tin foil 3uf200VDC to Miflex1uf 240VDC copper foil what are your thoughts will reducing the value to 1uf affect the bass and frequency response or should I go with a higher value than 3uf

I replaced the 4 small interstage caps in my pre. Given their small value of 0.01uF I elected to go with CuTF VCaps. I am blown away by the improvement given the mediocre 3.0uF signal caps are still in place. It sounds like angels are in my room singing to me. Strings just hang in the air and the low level detail is almost overwhelming.

I looked at a picture of the C1800. It is very different to my C800 and even uses different tubes. However, it looks like you possibly have the same small signal capacitors I have. If you have a multimeter you can confirm. It is much much much cheaper to replace those small caps than those big guys. And they do make a big difference.

I’m looking for 3uF caps and I cannot find Duelands of the appropriate value anywhere. The largest I’ve seen is 2.2uF and I’m way to risk averse to go that low.

I can get ODAMs but I see Chris V has some 3.0uF TFTFs available at a steep discount (albeit still not exactly cheap)

Have you compared ODAMs to TFTFs? I have used TFTFs in the past and I do like them but I’ve never heard the ODAM so any input would be appreciated.


Thanks in advance 
The Odams are far better! Nice job with the Cutf upgrade! Just wait till they break in fully! 
Thanks for your advice grannyring  - 4 ODAMs on their way. I’m not even going to put the cover back on. The ODAMs will be going in the minute they arrive.
