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
