MHDT Orchid with WE 396A Unbalanced
Hi everyone.
I recently picked up a used MHDT Orchid from Canuck audiomart. But I am yet to listen to it as my Tannoy MG15 in under refurbishment and I don't have anything else to listen it on. Orchid came with 4 tubes:
1) GE JAN 5670W NOS
2) Some 5670 made in USSR
I got the next 2 tested and they were found to be unbalanced.
3) WE 396A
Triode a -93℅ at 100v
Triode b-84℅ at 100v
4) Siemens Halske CCA 88 with adapter.
Triode a -93℅ at 100v
Triode b-84℅ at 100v
What do these measurements mean. Can they be used in the Orchid? Will an unbalanced tube cause any problem in the dac. Looking for guidance .
Thanks

@hilde45 Thanks, will do that. |
I own the Orchid DAC and use it regularly. The GE JAN 5670W tube is the standard tube that came with the DAC. The WE 396A was an upgrade tube option that a few years ago cost about $75 but I noticed now this tube is selling for 2x to 3x times that. The WE 396A is highly praised. Give it a listen. Don't understand you questions about the measurements or that they are unbalanced. You might want to post those questions on a tube forum. |
I have an Orchid and preferred the 6922 with adapter to the 5670. The 7311 seemed to extend the top end for me while the NOS bugle boy D getters sure were nice. As good as the DAC is I replaced it with PSAudio DirectStream DAC. It should be better it cost almost 5X the price of the Orchid new. I did not do the GrannyRing capacitor and resister upgrade but still have it so it would be fun to try it and see how it compares. Of course their is the DirectStream MK1 upgrade that is supposed to take it to the next level.... AHHH what a hobby. |
