I’ve had a Wellbrook 1530 for ages and one of its advantages over the MLA is its LF response. It receives well down to about 30kHz and I’ve even picked up SAQ Grimeton on 17.5 Khz on it – but it’s well down at that frequency. As I have an interest in the LF end of things, a wee while ago I bought one of Wellbrooks LF loop amplifiers and added my own 3-turn loop (1m dia) and was delighted to see much improved signals below 30 kHz and SAQ comes in well now.
The 3-turn loop limits its HF response though so I’ve put both loops up on the same rotator, mounted at right angles so there’s no coupling between them.
BTW, I spoke to Andy Ikin a few months ago and he says he is reducing his product range and as he’s getting on a bit now he may retire soon. It might be time to stock up..
