Regarding the speed and test-tape issues, the key is to compare using a known-good VCR. For example, if you play a tape recorded on the Hitachi on another machine, does it play properly? (And, switching the speed while a VCR is recording may not even work; you might have to hit Stop first. But, trying each speed available is a good plan.) Make sure your test VCR can play all the speeds of the Hitachi (so, don't use a VBT-200 or VCT-series machine to try to play an "SLP" or "EP" recording).

No I don't have a 'scope and I have said this several times before on here, I can't afford to get one because all of the 'scopes I've seen for sale on ebay are going for well over $100 and I don't have that kind of money laying around.
As for the test tape I couldn't even make a proper test tape because the tuner on the VCR isn't even working right so I had no way to get a test signal into the VCR for recording test purposes.
