+2 azimuth adjustment - Possible to damage tapes?

I've been trying to dial in the correct azimuth on my +2 and I noticed some tapes needed different adjustments. Anyway I was trying to find a happy medium but I've noticed some damage on the tapes I've been using, vertical impressions. I suspect I've been careless when tightening the adjustment scre...

Re: Video: ZX Spectrum 128K Toastrack Repair and Jailbar Reduction

My grey +2 has a mild case of jailbars through the RGB. Is there a similar fix?

No mention of Teenage Mutant Ninja Turtles?

The resistor I used is fairly old and cheap, could this affect the bass response?
Not very likely, but not impossible either.
Thought not. Thanks, you're being very helpful :)

Re: Acquired a near mint +2 - Modding advice needed.

wouldn't increasing the resistance of R80 reduce the audio level for the data interpreter? Not in the least. In fact, you could remove R80 entirely and it wouldn’t affect the loading of programs. though the AY output still sounds extremely thin. Yeah, that is a bit peculiar. Make sure there are no ...

Re: Acquired a near mint +2 - Modding advice needed.

*edit* Actually I'm a bit confused. If R45 affects Datacorder output volume what does R80 do? One resistor is in line with the input (R80) and the other with the output (R45). That was done so you could hear the sound if you saved data, too. They are not completely separate, however (at the ULA), s...

Re: Acquired a near mint +2 - Modding advice needed.

Wouldn't changing R45 reduce the level of the ULA audio? I'm hearing very clear beeper audio so I'd rather raise the AY volume to match the ULA otherwise both signals would be swamped in the background hum from the tapedeck's amplifier. Yes, it would, but there’s no way around it. You can’t drop th...

Acquired a near mint +2 - Modding advice needed.

I recently got given a near mint Speccy +2 and a nice 14" Sony Trinitron TV. It was quite an experience opening her up and seeing how clean and immaculate the internals were :D Anyway, the RF output is (as expected) messy but still better than I remember from my childhood. I eventually ordered an RG...
