My Sonneteer Alabaster makes quite a noise when switching on , particularly when the input selector is on phono , and then even more so when I power up the T/T with the Heed Orbit PSU/Speed controller. To stop this I power up the T/T then switch on the amp and later switch off amp first then T/T , is this ok I haven't really experienced this before with other amps.

I got shut of my Heed Its was noisey thing. I think i mentioned this to you a while back. If it's an 'Orbit 2' Could you remove it & just try the deck on its own just to see if its not that? Amazes me how i totally forget about everything ive learned thru the years & what pitfalls i know not to fall into again but yet i do..  |

The amp makes a noise with the Orbit 2 unplugged btw , I'll do a series of checks and note the outcomes. Yes the Orbit does make a small noise on its own but its so handy for the speed change. |

Did you not have an Alchemist 'Kraken' amp?

Any good with soldering iron, Mr B? If so, wire something like a 0.1/0.47uF 275v capacitor across the live side of the switch. |

Soldering is no problem, electronics is , I don't know anything about the insides of the equipment. |

What I'm basically asking is , is the amp ok , is it normal to make these noises?

Of this day & age. Amplifiers should be near enough silent.

What I'm basically asking is , is the amp ok , is it normal to make these noises? Probably. If it didn't used to make a switch-on noise then it's a sign of aging, but nothing to be concerned about unless it becomes drastic or starts sounding poor. Then I'd start by looking at the main electrolytic reservoir caps. |

Some do. Some don't. A said capacitor across the switch live connections could help. Not quite as simple as that. To be safe, the cap must be X or Y rated. Here's a simple filter that might do the trick. www.world-designs.co.uk/forum/showthread.php?t=149 |

Yes. Sorry. Should have said it should be a Class X or Y mains suppression type capacitor. And yes, a Delta-Type filter could be employed. But I have to say when was the last you saw one in a piece of gear you've opened up? For me, never. A basic capacitor across the live is what's likely to be found - like this one:  Despite looking a tad distressed - and you have to admit, it is looking distressed - it was still holding it's own, and hadn't actually shorted, a feature of Class X & Y capacitors. |

Ah, ok. Some models do that from new, so I wouldn't read anything into it.
As for switch-on order, it's always good practice to adopt source, pre, power amp on in that order. Reverse it for switch-off.

The power switch on the T/T is still active , is it worth wiring the power cord from the Heed direct to the motor , would there be any benefits . I leave the switch on all the time , seems silly to have two on switches. It also makes a noise through the amp btw when I do use it.

It depends on whether you want to keep the deck stock, or modify it.
Me, I'd bypass the switch and use the Heed to control the deck.

The Heed used to make the Red neon illuminturd Systemdek on/off switch flicker

Yes I think I'll do it ,I only paid £160 for it , I'm actually thinking about getting it veneered so I'll blank the switch hole. These decks are the Audio Note TT1 and they cost a tidy sum. |
