My dartzeel preamp needs to have its battery replaced and will be out of commission for 3 weeks while the work is performed.
The preamp is both line and phono. I will go bonkers without a preamp for 3 weeks. I don't need a line and phono for those 3 weeks. I would prefer to buy an inexpensive tube preamp that is compatible with my dartzeel amplifier and a shelter 501 mk2 mc low output. The dartzeel is set for 57 gain I believe.
What inexpensive tube preamp can be hooked up between my turntable (lenco L-75 with Rega arm) and my dartzeel amp as a backup preamp for backup situations like the one I will be facing.
