Thanks

Belafonte at Carnegie Hall (album recorded in 1959) is one of the first releases on the 1958 RIAA stereophonic standard.

Enjoy the stereophonic sound, which is even better than many new recordings.

Re. 1828

Leak TL12.1 was produced in 1948-55(?).

At that time monaural was the standard (2-channel stereo was established in 1958).

Can I use vintage Brimar 6L6G in the place of KT66 in the Leak 12.1?
----------------------------------------------------------

Duncan tubedata sheet shows that:

6L6 and 6L6G works at recommended maxium anode voltage of 360V for maximum 19W.

KT66 at max 500V for max 25W.

6L6GC at max 500V for max 30W.

Hence, 6L6G (and 6L6) is NOT recommended for Leak TL12.1.

Use 6L6GC or KT66 only!

Varislop II preamp - TL12.1 power amp

是否因為在單聲道年代 所以只需一部單聲道後級？

Gorgeous

Very much mint looking comb of Varislop II preamp - TL12.1 power amp.

How does its mate look like?

My 12.1

Nice two pairs!
I wish you can operate them soon.

Pair 1 (on wooden plint) :

They, the internal, look good . The thing to consider is to replace the plastic boxed metal film capacitors with paper-in-oil modern ones. There are lots of offers in the market or internet. 0.25uF/500-600VDC each.

Pair 2 :

These look like for professional use because they each has a input transformer (the black round ones). Interesting further is how you would handle these input transformers? Skip them to make them like Pair 1, or keep them (but then how you would use the amps?).

thank you for allowing me to show them.
I am in South Africa.

Both pairs work but Pair 2 has not been switched on in 10 years and is currently with my technician for a restoration and recap.

Pair 1 was previously recapped by someone else and mounted on a wooden plinth but is working fine. I will remove the plinth soon.

I need a pair of ECC33 for Pair 2.
