Re: Doc modding Marantz imperial 7

If you are in a situation where the speaker enclosure is too big ( can't happen very often) for the driver then how do you deal with this. J expect most would put a load of bracing in and kill two birds with one stone. I have heard of bricks and such things put inside. I was going to put sand inside...

Re: Another DIY SS Amplifier with NVA Boards

An alternative to simply attenuating the input is increasing the feedback ratio of the amp. This has other advantages too. The NVA circuit normally has about 30dB of gain. You can drop 3dB out of this by dropping the series 18k resistor to 10k. It's this one. Thanks. I’ll have a look at that option...

Re: Doc modding Marantz imperial 7

Yeah, suck it and see is the obvious way to go about this. I don't want to spend forever trying different stand materials as this speaker saga has taken long enough already. I am keen to have a mix of materials in these speakers. In my tiny brain I think this will possibly help to average the sound ...

Re: Doc modding Marantz imperial 7

I guess I can try different uprights but there is a trade off I believe. Heavy versus light. Many people including Savvy prefer light to heavy. I have not done any real comparisons. If I was to go with a solid upright I would probably use the solid 70mm brass bar I have although concrete would proba...

The George Benson Cookbook. Third studio albulm released in 1967 and produced by John Hammond. Benson really is a killer guitarist and this album like his other early works would all sound right at home in the funky Blue Note jazz Catalogue (it's on Columbia though). https://upload.wikimedia.org/wik...

Not much progress here but thinking and chin scratching :think: I have rescued these 35cm circular discs which were the seats on a couple of breakfast bar stools - long since rusted. The finest fake wood :grin: https://i.imgur.com/roMl34k.jpg I keep getting these fancy ideas which turn out to be rea...

Re: HAPPY HOLIDAYS

Last day of holidays for me. Looking after kids before they go back to school tomorrow. I must say it has been one of the worst festive periods I can remember. Only surpassed by the one in my early 20's when I spent three weeks in bed with glandular fever eating only soup. Sunday was my first day of...
