Dear Doc, Ki and Ironbut
Many thanks for your quick responses and your suggestions.
The heads are very clean, having the 1500 for about 3 weeks, the heads have been cleaned at least 3 times (weekly).
With the exception of a few quick trials using some older tape to make sure that everything was working, the only tapes that has been payed
are TP tapes (The Band and The Staple Singers...that's all that were available..I'm waiting for Eileen to call me when the balance of my selections come in)
I did visit my local electronic guru (he is an ex Studer technician) and had him do a careful head alignment on his scope. In fact my first inclination was that the heads were out of alignment. Any small misalignment has now been corrected using his (TEAC company issued) test tape. According to the scope, we have a nice clean flat 20-20 response.
As for the direct out head rewiring, I presume the technican just re-routed directly out to the RCA's.
Could it be a bad tube ? Is it possible that something happened to the Eros in transit (Eileen told me that Sean checked it carefully and it sounded great before shipping) ? Is it time for new heads (I think they look ok)...before I have to send the headblock off to Fluxmagnetics (for new heads) I was hoping to find a less expensive solution.
I'm grateful for any other suggestions..
Thank you
