I think I wrote clearly...

NO

Hey, the CATO is on sale...

Welborne Labs CATO Vacuum Tube Linestage

It looks like a good output option for the ak4396 dac. (but I guess ak4396 doesn't need a i/v converter).

It is a voltage output dac, so no i/v converter needed.

However, the analog buffer on the output looks like it forms a butterworth second order filter, and if you bypass it to drive the tube amp directly you will need t0 add a filter.

OPA627: 4$ on e-bay, including soldered on an adapter for SIL insertion.
OPA827 +/- 8$ but you need to solder the SMD yourself to an adapter

For comparison:

Farnell:
OPA627: € 32,50
OPA827: € 15,00 (also, only in SMD possible)

RS components:
OPA627: € 28,69 (in SMD)
OPA827: € 7,91 (in SMD)

Mouser:
OPE627: € 14,81 (SIL)
OPA827: € 8,17 (in SMD)


Interesting price range.

Benefit of RS, Farnell, Mouser etc.... Order today, receive tomorrow. With E-bay through China, it takes 3-4 weeks. But heck... 4$ for a OPA627.... or € 14 through Mouser (with € 20 shipping)..... Choice is easy.


But... I see that both op-amps are single only. The NE5532 is a dual. So I need a conversion socket?

Is the OPA627 a drop in replacement for the NE5532?
