Customer service

Not sure what’s exceptional?   You paid an extra $25 for expedited shipping which has nothing to do with the vendor.  Give praise to the shipping company when the whole world shipping stuff like crazy. 

How do you like the Acme 845's and what did they replace in your amp?  I'm considering trying the Acme 805's and would likely get them through Grant as well.  I ordered a Psvane rectifier from them a few months ago w/o expedited shipping and it arrived in about 10 days.  I rarely have a "tube emergency" that requires paying $25 extra but it's nice that they offer the option.

Grant Fidelity is first class. Please let us know what you think of your new tubes.

3ez and Iwin I will keep you posted once I get about 50 hours on these new tubes. They replaced the stock tubes in my line magnetic 845 ia.Warmest regards
